• How to setup a development Active Directory

  - by Rob

  Does anyone have any suggestions on how to setup a development environment for active directory? We are thinking of using development.contoso.com or something along those lines that is a completely separate envnironment from our production. This will be used for things like Dev SharePoint and possibly a Dev exchange server. Maybe even a dev CRM. We are thinking of setting this up all using virtual machines. Possibly having the production get replicated down on a regular basis as well. Does anyone have an experience with this or any suggestions on what to do or not to do for this?

• How do I clone an OpenLDAP database

  - by elzapp

  I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.

• IP blocked because: (smtpauth) Failed SMTP AUTH login from - can someone explain?

  - by gdaniel

  Today I had a few users blocked in our server firewall because of: (smtpauth) Failed SMTP AUTH login from Can someone explain the reason? What does it exactly mean? Could someone be using the our website to access SMTP for spamming purpose? UPDATE: Server info: Centos OS with CPanel and WHM. However no one has access to either. Taking a look at the logs it looks like someone repetitively attempted to login with a known existent user/pass.

• Enable basic auth sitewide and disabling it for subpages?

  - by piquadrat

  I have a relatively straight forward config: upstream appserver-1 { server unix:/var/www/example.com/app/tmp/gunicorn.sock fail_timeout=0; } server { listen 80; server_name example.com; location / { proxy_pass http://appserver-1; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; auth_basic "Restricted"; auth_basic_user_file /path/to/htpasswd; } location /api/ { auth_basic off; } } The goal is to use basic auth on the whole website, except on the /api/ subtree. While it does work with respect to basic auth, other directives like proxy_pass are not in effect on /api/ as well. Is it possible to just disable basic auth while retaining the other directives without copy&pasting everything?

• Why does a browser dialog come up when an xmlhttprequest sends the wrong / no auth?

  - by Kyle

  How come the major browsers all bring up a login dialog when an xmlhttprequest does auth wrong or doesn't send it? I mean isn't this poor UI? Now a days it seems like a lot of people try http auth in jQuery, because theoretically it is quite easy - until the user fails to enter the correct data and is presented with the browsers dialog, which gets in their way, and they might have no idea what to do with it or why it's there? I don't know too much about these low level browser specifications but can someone bring this up with the RFC or webkit/gecko developers? jQuery digest auth could be powerful and user friendly if this was fixed. ** It seems like apache could also fix the problem on their side by not sending the header, but whichever one is the most secure way of doing this would be nice.

• How can I exclude a file in a folder from basic auth (regex help)?

  - by simon180

  Hi I have a folder on my site which contains admin files and I've added basic auth following a little unwanted attention. This works fine however a couple of the admin functions won't work through basic auth as they handle file uploads and so I want to exclude these files from the auth. It shouldn't have any security implications as any rogue user wouldn't be able to access the pages that could create a session to use these functions. I am using the following basic code to exclude a file: <FilesMatch "(index.php\/myadminfolder\/myurl\/myaction/someotherstuff?)$"> Satisfy Any Order allow,deny Allow from all Deny from none </FilesMatch> The URL exclusion is not working. The URL to exclude is in the form: index.php/directory/subdirectory/action/uniqueid/blah What is the correct URL string to add to FilesMatch to exclude any files that start with the pattern of index.php/directory/subdirectory/action - regardless of what comes after action? Thanks Simon

• How do I configure apache to accept a client ssl certificate (if present) or authenticate using ldap (if the cert is absent)?

  - by jmwood051

  I have an Apache server that serves up mercurial repositories and it currently authenticates using ldap credentials. I want to permit a single user (to start with) to use a SSL client certificate, with all remaining users still able to use the ldap credentials authentication method. I have looked through Stack Overflow and other wider (google) searches but can not find information/guidance on how to set this up.

• zend framework 2 autentification using DbTable failure

  - by josepmra

  I have followed the zend instructions for implement my web Authentication using a database table. It's exactly the same code, but when render the page, the following exceptions appears: Zend\Authentication\Adapter\Exception\RuntimeException File: C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Authentication\Adapter\DbTable.php Mensaje: The supplied parameters to DbTable failed to produce a valid sql statement, please check table and column names for validity. produced by this other: Zend\Db\Adapter\Exception\InvalidQueryException File: C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Db\Adapter\Driver\Mysqli\Statement.php Mensaje: Statement couldn't be produced with sql: SELECT `users`.*, (CASE WHEN `password` = ? THEN 1 ELSE 0 END) AS `zend_auth_credential_match` FROM `users` WHERE `mail` = ? Seems to be that Statement.php can not execute the sql of above, but I send the sql by phpmyadmin replacing the ? for strings and work ok. I am sure that $dbAdapter works ok also because I have tested it and the columns name are "mail" and "password". This in my code, also I put the $dbAdapter test code. $dbAdapter = new DbAdapter(array( //This DbAdapter Work ok sure!! 'driver' => 'Mysqli', 'database' => 'securedraw', 'username' => 'root', 'password' => '' )); $fp = function($name) use ($dbAdapter) { return $dbAdapter->driver->formatParameterName($name);}; $sql = 'SELECT * FROM ' . $qi('users') . ' WHERE id = ' . $fp('id'); $statement = $dbAdapter->query($sql); $parameters = array('id' => 1); $sqlResult = $statement->execute($parameters); $row = $sqlResult->current(); $mail = $row['mail']; $password = $row['password']; //until here test $dbAdapter exitly!! //Start the auth proccess!! $authAdapter = new AuthDbTableAdapter($dbAdapter); $authAdapter->setTableName('users') ->setIdentityColumn('mail') ->setCredentialColumn('password'); $authAdapter->setIdentity('josep') ->setCredential('josep'); $authResult = $authAdapter->authenticate(); //This is the fail method!!!

• Should we develop a custom membership provider in this case?

  - by Allen

  I'll be adding a bounty to this, probably 200, more if you guys think its appropriate. I wont accept an answer until I can add a bounty so feel free to go ahead and answer now Summary Long story short, we've been tasked with gutting the authentication and authorization parts of a fairly old and bloated asp.net application that previously had all of these components written from scratch. Since our application isn't a typical one, and none of us have experience in asp.net's built in membership provider stuff, we're not sure if we should roll our own authentication and authorization again or if we should try to work within the asp.net membership provider mindset and develop our own membership provider. Our Application We have a fairly old asp.net application that gets installed at customer locations to service clients on a LAN. Admins create users (users do not sign up) and depending on the install, we may have the software integrated with LDAP. Currently, the LDAP integration bulk-imports the users to our database and when they login, it authenticates against LDAP so we dont have to manage their passwords. Nothing amazing there. Admins can assign users to 1 group and they can change the authorization of that group to manage access to various parts of the software. Groups are maintained by Admins (web based UI) and as said earlier, granted / denied permissions to certain functionality within the application. All this was completely written from the ground up without using any of the built in .net authorization or authentication. We literally have IsLoggedIn() methods that check for login and redirect to our login page if they aren't. Our Rewrite We've been tasked to integrate more tightly with LDAP, they want us to tie groups in our application to groups (or whatever types of containers that LDAP uses) in LDAP so that when a customer opt's to use our LDAP integration, they dont have to manage their users in LDAP AND in our application. The new way, they will simply create users in LDAP, add them to Groups in LDAP and our application will see that they belong to the appropriate LDAP group and authenticate and authorize them. In addition, we've been granted the go ahead to completely rip out the User authentication and authorization code and completely re-do it. Our Problem The problem is that none of us have any experience with asp.net membership provider functionality. The little bit of exposure I have to it makes me worry that it was not intended to be used for an application such as ours. Though, developing our own ASP.NET Membership Provider and Role Manager sounds like it would be a great experience and most likely the appropriate thing to do. Basically, I'm looking for advice, should we be using the ASP.NET Membership provider & Role Management API or should we continue to roll our own? I know this decision will be influenced by our requirements so I'm going over them below Our Requirements Just a quick n dirty list Maintain the ability to have a db of users and authenticate them and give admins (only, not users) the ability to CRUD users Allow the site to integrate with LDAP, when this is chosen, they don't want any users stored in the DB, only the relationship between Groups as they exist in our app / db and the Groups/Containers as they exist in LDAP. .net 3.5 is being used (mix of asp.net webforms and asp.net mvc) Has to work in ASP.NET and ASP.NET MVC (shouldn't be a problem I'm guessing) This can't be user centric, administrators need to be the only ones that CRUD (or import via ldap) users and groups We have to be able to Auth via LDAP when its configured to do so I always try to monitor my questions closely so feel free to ask for more info. Also, as a general summary of what I'm looking for in an answer is just. "You should/shouldn't use xyz, here's why". Links regarding asp.net membership provider and role management stuff are very welcome, most of the stuff I'm finding is 5+ years old. Edit: Added some stuff to "Our Rewrite"

• Can't install new database in OpenLDAP 2.4 with BDB on Debian

  - by Timothy High

  I'm trying to install an openldap server (slapd) on a Debian EC2 instance. I have followed all the instructions I can find, and am using the recommended slapd-config approach to configuration. It all seems to be just fine, except that for some reason it can't create my new database. ldap.conf.bak (renamed to ensure it's not being used): ########## # Basics # ########## include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel none modulepath /usr/lib/ldap # modulepath /usr/local/libexec/openldap moduleload back_bdb.la database config #rootdn "cn=admin,cn=config" rootpw secret database bdb suffix "dc=example,dc=com" rootdn "cn=manager,dc=example,dc=com" rootpw secret directory /usr/local/var/openldap-data ######## # ACLs # ######## access to attrs=userPassword by anonymous auth by self write by * none access to * by self write by * none When I run slaptest on it, it complains that it couldn't find the id2entry.bdb file: root@server:/etc/ldap# slaptest -f ldap.conf.bak -F slapd.d bdb_db_open: database "dc=example,dc=com": db_open(/usr/local/var/openldap-data/id2entry.bdb) failed: No such file or directory (2). backend_startup_one (type=bdb, suffix="dc=example,dc=com"): bi_db_open failed!

It doesn't resolve the underlying problem: root@server:/etc/ldap# slaptest -f ldap.conf.bak -F slapd.d -u config file testing succeeded Looking in the database directory, the basic files are there (with right ownership, after a manual chown), but the dbd file wasn't created: root@server:/etc/ldap# ls -al /usr/local/var/openldap-data total 4328 drwxr-sr-x 2 openldap openldap 4096 Mar 1 15:23 . drwxr-sr-x 4 root staff 4096 Mar 1 13:50 .. -rw-r--r-- 1 openldap openldap 3080 Mar 1 14:35 DB_CONFIG -rw------- 1 openldap openldap 24576 Mar 1 15:23 __db.001 -rw------- 1 openldap openldap 843776 Mar 1 15:23 __db.002 -rw------- 1 openldap openldap 2629632 Mar 1 15:23 __db.003 -rw------- 1 openldap openldap 655360 Mar 1 14:35 __db.004 -rw------- 1 openldap openldap 4431872 Mar 1 15:23 __db.005 -rw------- 1 openldap openldap 32768 Mar 1 15:23 __db.006 -rw-r--r-- 1 openldap openldap 2048 Mar 1 15:23 alock (note that, because I'm doing this as root, I had to also change ownership of some of the files created by slaptest) Finally, I can start the slapd service, but it dies in the attempt (text from syslog): Mar 1 15:06:23 server slapd[21160]: @(#) $OpenLDAP: slapd 2.4.23 (Jun 15 2011 13:31:57) $#012#011@incagijs:/home/thijs/debian/p-u/openldap-2.4.23/debian/build/servers/slapd Mar 1 15:06:23 server slapd[21160]: config error processing olcDatabase={1}bdb,cn=config: Mar 1 15:06:23 server slapd[21160]: slapd stopped.

Unfortunately, syslog isn't reporting a specific error in this case (if it were a file permission error, it would say). I've tried uninstalling and reinstalling slapd, changing permissions, Googling my wits out, but I'm tapped out. Any OpenLDAP genius out there would be greatly appreciated!

• OpenLDAP mirror mode replication failing with TLS behind a load balancer

  - by Lynn Owens

  I have two OpenLDAP servers that are both running TLS. They are: ldap1.mydomain.com ldap2.mydomain.com I also have a load balancer cluster with a dns name of it's own: ldap.mydomain.com The SSL certificate has a CN of ldap.mydomain.com, with SANs of ldap1.mydomain.com and ldap2.mydomain.com.

• PostgreSQL user authentication against PAM

  - by elmuerte

  I am trying to set up authentication via PAM for PostgreSQL 9.3. I already managed to get this working on an Ubuntu 12.04 server, but I am unable to get this working on a Centos-6 install. The relevant pg_hba.conf line: host all all 0.0.0.0/0 pam pamservice=postgresql93 The pam.d/postgressql93 is the default config shipped with the official postgresql 9.3 package: #%PAM-1.0 auth include password-auth account include password-auth When a user tries to authenticate the following is reported in secure log: hostname unix_chkpwd[31807]: check pass; user unknown hostname unix_chkpwd[31808]: check pass; user unknown hostname unix_chkpwd[31808]: password check failed for user (myuser) hostname postgres 10.1.0.1(61459) authentication: pam_unix(postgresql93:auth): authentication failure; logname= uid=26 euid=26 tty= ruser= rhost= user=myuser The relevant content of password-auth config is: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so The problem is with the pam_unix.so. It is unable to validate the password, and unable to retrieve the user info (when I remove the auth entry of pam_unix.so). The Centos-6 install is only 5 days old, so it does not have a lot of baggage. The unix_chkpwd is suid and has execute rights for everybody, so it should be able to check the shadow file (which has no privileges at all?).

  First, sorry for my english and my poor knowlodge of this subject. I have a dedicated server placed in Germany (windows 2008 R2) and I live in spain. I would like to access internet from my home computer (Windows 7 Pro x64), trough my server in Germany, so I can use a German IP, what I need some times.

• login as rsh in rhel 6 without entering password

  - by cartmancakes

  I need to be able to login to a RHEL 6 server using rsh (please don't flame me about security, it's irrelevant in this particular instance) as root without having to enter a password. My procedure for setting this up works great in RHEL 5.x, but does not work in RHEL 6. I suspect this has something to do with PAM, but I'm inexperienced with how to use PAM. Can someone help me with this? /etc/pam.d/rsh auth required pam_rhosts.so auth required pam_nologin.so account include common-account password include common-password session required pam_loginuid.so session include common-session /etc/pam.d/rlogin auth required pam_nologin.so auth [user_unknown=ignore success=ok ignore=ignore auth_err=die default=bad] pam_securetty.so auth sufficient pam_rhosts.so auth include common-auth auth required pam_mail.so account include common-account password include common-password session required pam_loginuid.so session include common-session Thanks!

• Cannot SSH anymore, what went wrong?

  - by lbwtz2

  I use to ssh to a remote server (no rsa-key, just password). Now the server do not accept the connection any more and throw me this error: ssh_exchange_identification: Connection closed by remote host While I can google a little to find a fix I can't figure out what went wrong since I haven't touched anything on the machine since last login. Can you help me find the cause? EDIT: Inspecting the logs I've found these: /var/auth.log /var/log/auth.log:Dec 26 16:40:32 vps sshd[15567]: error: fork: Cannot allocate memory /var/log/auth.log:Dec 26 16:41:05 vps sshd[15567]: error: fork: Cannot allocate memory /var/log/auth.log:Dec 26 16:43:47 vps sshd[15567]: error: fork: Cannot allocate memory /var/log/auth.log:Dec 27 03:20:06 vps sshd[15567]: error: fork: Cannot allocate memory /var/log/auth.log:Dec 27 16:15:02 vps sshd[15567]: error: fork: Cannot allocate memory And in the same span-time I've also found a lot of these: /var/log/auth.log:Dec 26 13:00:01 vps CRON[1716]: PAM unable to dlopen(/lib/security/pam_unix.so): libcrypt.so.1: cannot map zero-fill pages: Cannot allocate memory /var/log/auth.log:Dec 26 13:00:01 vps CRON[1716]: PAM adding faulty module: /lib/security/pam_unix.so What are these?

• Can OpenVPN be set up so the server doesn't have interface that is part of the VPN?

  - by BCS

  I'm looking to set up a VPN (OpenVPN is my first choice but I'm not stuck with it) in such a way that the server that hosts the VPN is not visible from within the VPN. That is; any packet that a client sends via the VPN interface will get delivered to another client's VPN interface or get dropped. In the other direction, the server shouldn't have a VPN interface at all and normal network operations shouldn't be able to send packets on the network. Can this be done? All the docs I have found have assumed that clients will connect via DHCP (this requiring that the server connect at least to that extent) but I can't think of any reason that a VPN couldn't use static IP's or that the DHCP server couldn't be implemented inside the VPN (see edit) server without setting up a VPN interface on the server. Edit: Based on the link on bridged mode from Phil Hollenback's answer it seems that OpenVPN does in fact have the "internal DHCP server" that I'm thinking of.

• 550 5.7.1 our Bulk Email Senders Guidelines

  - by darkandcold

  Hello, I moved to a new server with integrated merak mail. since I forgot merak(used before), i missed to configure security options. So before I realize the issue, my smtp server was used by spammers for 2 days, hundreds times I configured security settings as what it should be (at least i hope) then i realize, i can't send e-mail to gmail or hotmail. gmail says "550 5.7.1 see our Bulk Email Senders Guidelines" yes, I saw its guidelines. first, I creat SPF records via msn senderID wizard. it completed very well. then as gmail says, I created DKIM dns records. (in Merak mail, there is option to create DKIM, i created it and save it to DNS as TXT record) it's been 2 days after doing the fixes above. but still i can't send mail gmail or hotmail. (P.S, some of my domain in merak is forwarded to my gmail account i mean when a mail arrives to [email protected] it will forward to my gmail. and the surprise it, merak mail can forward them very vell :S but can't still send mail from outlook etc.)
