    - by borjamf
    im trying to connect LDAP over StartTLS but Im stuck with an issue. I've followed step by step this guide https://help.ubuntu.com/12.04/serverguide/openldap-server.html#openldap-tls and LDAP it's working OK as well as "ldapsearch -xZZ -h 172.25.80.144" on my Ubuntu Sever 12.04 However, in my Ubuntu Desktop 11.04 Client I get this error: ldapsearch -x -H 172.25.80.144 -ZZ ldap_start_tls: Connect error (-11) additional info: **TLS: hostname does not match CN in peer certificate** Server /etc/ldap/ldap.conf BASE dc=prueba,dc=borja URI ldap://prueba.borja SIZELIMIT 12 TIMELIMIT 15 DEREF never TLS_CACERT /etc/ssl/certs/ca-certificates.crt Client /etc/ldap.conf ssl start_tls tls_checkpeer no /etc/ldap/ldap.conf BASE dc=prueba,dc=borja URI ldap://prueba.borja SIZELIMIT 12 TIMELIMIT 15 DEREF never TLS_REQCERT allow Anybody could tell me how to fix this?

  • Performance analytics via DBMS "plugins", or other solution

    - by Polynomial
    I'm working on a systems monitoring product that currently focuses on performance at the system level. We're expanding out to monitoring database systems. Right now we can fetch simple performance information from a selection of DBMS, like connection count, disk IO rates, lock wait times, etc. However, we'd really like a way to measure the execution time of every query going into a DBMS, without requiring the client to implement monitoring in their application code. Some potential solutions might be: Some sort of proxy that sits between client and server. SSL might be an issue here, plus it requires us to reverse engineer and implement the network protocol for each DBMS. Plugin for each DBMS system that automatically records performance information when a query comes in. Other problems include "anonymising" the SQL, i.e. taking something like SELECT * FROM products WHERE price > 20 AND name LIKE "%disk%" and producing SELECT * FROM products WHERE price > ? AND name LIKE "%?%", though this shouldn't be too difficult with some clever parsing and regex. We're mainly focusing on: MySQL MSSQL Oracle Redis mongodb memcached Are there any plugin-style mechanisms we can utilise for any of these? Or is there a simpler solution?

  • Is there a simple LDAP-to-HTTP gateway out there?

    - by larsks
    We have a local LDAP directory that provides basic contact information about our user community. We would like to integrate this into some third-party hosted services that allow us to implement widgets that run arbitrary Javascript. In order to connect Javascript to our LDAP directory, I would like to set up a simple LDAP-to-HTTP proxy that would accept HTTP GET requests, translate them into an appropriate LDAP query, and respond with directory information as JSON-encoded data. In an ideal world, something like this: GET /[email protected] Would get me something like this: { "cn": "Bob Person", "title": "System Administrator", "sn": "Person", "mail": "[email protected]", "telepehoneNumber": "617-555-1212", "givenName": "Bob" } (And this obviously assumes that the web application has locally configured information about what base DN to use, how to authenticate, etc). I guess I could write one...but surely something like this already exists? UPDATE The consensus seems to be that there isn't a pre-existing solution out there and that I should just get off my lazy derriere and write one. So I did, and it's here. It's not especially pretty, but it works for my prototyping and I figure maybe someone else will find it useful someday.

  • How to move SharePoint authentication from AD to LDAP without breaking user profiles?

    - by Dan
    We have a bunch of users in a local Active Directory OU that access the SharePoint portal. We've just added LDAP authentication and pointed it at the organisation's global LDAP server, so out AD accounts are now redundant. Is there a way to re-map the authentication for a SharePoint (MOSS 2007) user/profile. That is, can we manually change a lot of users so that they log in with their LDAP credentials and get the same SharePoint MySite, groups, etc. as when they were authenticating via AD?

  • Can an LDAP query on AD provide the netbios domain name for a single account when using the Global Catalog?

    - by Kirk Liemohn
    I am using ADSI Edit to look at LDAP properties of a single user account in AD. I see properties such as userPrincipalName, but I do not see one for the fully qualified domain name (FQDN) or the netbios domain name. We will be setting up the Global Catalog (GC) to give us LDAP access to multiple domains and through configuration in an application we map LDAP properties to user profile properties within the application. With typical AD the FQDN and netbios domain name are the same for all users, but with the GC involved we need this additional information. We really only need the netbios domain name (the FQDN is not good enough). Maybe there is a LDAP query that can be done to request this information from a more top-level object in AD?

  • LDAP object class violation: attribute ou not allowed in suffix?

    - by Paramaeleon
    I am about to set up a LDAP directory. It is used as a tool to communicate user permissions from a web application to WebDav file system access, e.g. adding a user to the web platform shall allow login to the file system with the same credentials. There are no other usages intended. Following this German tutorial which encourages the use of the attributes c, o, ou etc. over dc, I configured the following suffix and root: suffix "ou=webtool,o=myOrg,c=de" rootdn "cn=ldapadmin,ou=webtool,o=myOrg,c=de" Server starts and I can connect to it by LDAP Admin, which reports “LDAP error: Object lacks”. Well, there aren’t any objects yet. I now want to create the root and admin elements from shell. I created an init.ldif file: dn: ou=webtool,o=myOrg,c=de objectclass: dcObject objectclass: organization dc: webtool o: webtool dn: cn=ldapadmin,ou=webtool,o=myOrg,c=de objectclass: organizationalRole cn: ldapadmin Trying to load the file runs into an error, telling me that ou is not allowed: server:~ # ldapadd -x -D "cn=ldapadmin,ou=webtool,o=myOrg,c=de" -W -f init.ldif Enter LDAP Password: adding new entry "ou=webtool,o=myOrg,c=de" ldap_add: Object class violation (65) additional info: attribute 'ou' not allowed I am not using ou anywhere except in the suffix, so the question: Isn’t it allowed here? What is allowed here? Here is my answer. I am not allowed to post it as answer for 8 hours, so don’t mind that it is part of the question by now. I will move it outside some day, if I don’t forget to do so. There are numberous dependencies for the creation of elements, and error messages are rather confusing if you don’t know of the concept. The objectclass isn’t necessarily dcObject for the databases’ root node, as it is likely to guess when you read several tutoriales. Instead, it must correspond to the object’s type: Here, for a name starting with ou=, it must be organizationalUnit. I found this piece of information in these tables [Link removed due to restriction: Oops! Your edit couldn't be submitted because: We're sorry, but as a spam prevention mechanism, new users can only post a maximum of two hyperlinks. Earn more than 10 reputation to post more hyperlinks. Link is below]. Further on, the object class dictates which properties must and can be added in the record. Here, organizationalUnit must have an ou: entry and must not have neither dc: nor o: entry. The healthy init.ldif file looks like that: dn: ou=webtool,o=myOrg,c=de objectclass: organizationalUnit ou: LDAP server for my webtool dn: cn=ldapadmin,ou=webtool,o=myOrg,c=de objectclass: organizationalRole cn: ldapadmin Note: The page also states: “While many objectClasses show no MUST attributes you must (ouch) follow any hierarchy […] to determine if this is the really case.” I thought that would mean my root record would have to provide the must fields for c= and o= (c: and o:, respectively) but this isn’t the case.

  • How can I proxy multiple LDAP servers, and still have grouping of users on the proxy?

    - by Chris
    I have 2 problems that I'm hoping to find a common solution to. First, I need to find a way to have multiple LDAP servers (Windows AD's across multiple domains) feed into a single source for authentication. This is also needed to get applications that can't natively talk to more than one LDAP server to work. I've read this can be done with Open LDAP. Are there other solutions? Second, I need to be able to add those users to groups without being able to make any changes to the LDAP servers I'm proxying. Lastly, this all needs to work on Windows Server 2003/2008. I work for a very large organization, and to create multiple groups and have large numbers of users added to, moved between, and removed from them is no small task. This normally requires tons of paperwork and a lot of time. Time is the one thing we don't normally have; dodging the paperwork is just a plus. I have very limited experience in all this, so I'm not even sure what I'm asking will make sense. Atlassian Crowd comes close to what we need, but falls short of having it's own LDAP front end. Can anyone provide any advice or product names? Thanks for any help you can provide.

  • Dealing with LDAP failure when using it for PAM/NSS?

    - by Insyte
    I use a redundant pair of OpenLDAP servers for PAM auth and directory services via NSS. It's been 100% reliable so far, but nothing runs flawlessly forever. What steps should I take now so I have a fighting chance of recovering from failure of the LDAP server(s)? In my informal testing, it appears that even already authenticated shells are largely useless as all username/uid lookups hang until the directory server comes back. So far I've come up with only two things: Do not use NSS-LDAP and PAM-LDAP on the LDAP servers themselves. Create a root-level account on all boxes that only accepts publickey authentication from our local subnet and protect that key well. I'm not sure how much good this would do me as once I'm logged in, I suspect I wouldn't be able to accomplish anything since all the userid lookups would be hanging. Any other suggestions?

  • Can My Personal GMail Query A Remote LDAP Server?

    - by Maarx
    I have a personal GMail account, from which I frequently send e-mail to a great many various users of a specific business. The corporation has been kind enough to provide me with the credentials to access their LDAP server, with which I would like my GMail web client to be able to auto-complete partial addresses or names for which that LDAP server has an entry. Is there any way I can get a personal GMail account (or it's corresponding entire Google account) account to incorporate an LDAP server into it's Contacts?

  • Data loss when downloading data from LDAP server

    - by Ricky D'Amelio
    Hi there. This question comes from a previous one I asked about handling NSData objects: http://stackoverflow.com/questions/2453785/converting-nsdata-to-an-nsstring-representation-is-failing. I have reached the point where I am taking an NSImage, turning it into NSData and uploading those data bytes to the LDAP server. I am doing this like so; //connected successfully to LDAP server above... struct berval photo_berval; struct berval *jpegPhoto_values[2]; photo_berval.bv_len = [photo length]; photo_berval.bv_val = [photo bytes]; jpegPhoto_values[0] = &photo_berval; jpegPhoto_values[1] = NULL; mod.mod_type = "jpegPhoto"; mod.mod_op = LDAP_MOD_REPLACE|LDAP_MOD_BVALUES; mod.mod_bvalues = jpegPhoto_values; mods[0] = &mod; mods[1] = NULL; //perform the modify operation rc = ldap_modify_ext_s(ld, givenModifyEntry, mods, NULL, NULL); That happens with no errors, and you can see a big blob of data when you're in the command line. My problem is, when I go to access the same data at a later stage, I am getting an image file back that's about 120 times smaller than the original image. //find the jpegPhoto attribute photoA = ldap_first_attribute(ld, photoE, &photoBer); while (strcasecmp(photoA, "jpegphoto") != 0) { photoA = ldap_next_attribute(ld, photoE, photoBer); } //get the value of the attribute if ((list_of_photos = ldap_get_values_len(ld, photoE, photoA)) != NULL) { //get the first JPEG photo_data = *list_of_photos[0]; selectedPictureData = [NSData dataWithBytes:&photo_data length:sizeof(photo_data)]; [selectedPictureData writeToFile:@"/Users/username/Desktop/Photo 2.jpg" atomically:YES]; NSLog (@"%@", selectedPictureData); Has anyone successfully done this before or can anyone see what I might be doing wrong? I appreciate anyone's help. Sorry to post so many questions! Ricky.

  • ForeignSecurityPrincipals with LDAP connection on Active Directory servers with trusted forest

    - by Killerwhile
    The context is the following : Two domains mutually trusted dc=dom1 dc=dom2 a group cn=group1,ou=someou,dc=dom1 with users inside : cn=user11,ou=anotherou,dc=dom1 cn=user12,ou=anotherou,dc=dom1 cn=user13,ou=anotherou,dc=dom1 cn=user21,ou=anotherou,dc=dom2 cn=user22,ou=anotherou,dc=dom2 cn=user23,ou=anotherou,dc=dom2 The questions : 1. Test user's credentials How can I do a ldap bind to test credentials for users of dom2 ? I tried to bind as usual but I cannot authenticate users of dom2, even if I connect in ldaps. Is there any trick ? Special permissions to set ? 2. Search and display users from the group. How can I retrieve the detailed informations about the users of dom1 and dom2 using LDAP(s) connection on the AD of dom1 ? I have an technical user which has right to browse both domain. I'm able to see 6 entries in the group with the following filter : (&(memberOf=cn=group1,ou=someou,dc=dom1)(|(objectClass=user)(objectClass=foreignSecurityPrincipal))) but the users from the other domain are seen as cn=...(some key)...,cn=foreignSecurityPrincipal,dc=dom1 Java hints would be better. Thanks a lot !

  • LDAP Query for OU's

    - by Stephen Murby
    Sorry for being an uber pain people, its all very new :( Already had alot of help on this, but don't seem to be able to see the problem, I am trying to populate a combo box with a list of all the current OU's, later to send each machine within that OU a shutdown command. (Acquiring AD OU list & Active Directory list OU's) were my previous Q's. string defaultNamingContext; //TODO 0 - Acquire and display the available OU's DirectoryEntry rootDSE = new DirectoryEntry("LDAP://RootDSE"); defaultNamingContext = rootDSE.Properties["defaultNamingContext"].Value.ToString(); DirectoryEntry entryToQuery = new DirectoryEntry ("LDAP://" + defaultNamingContext); MessageBox.Show(entryToQuery.Path.ToString()); DirectorySearcher ouSearch = new DirectorySearcher(entryToQuery.Path); ouSearch.Filter = "(objectCatergory=organizationalUnit)"; ouSearch.SearchScope = SearchScope.Subtree; ouSearch.PropertiesToLoad.Add("name"); SearchResultCollection allOUS = ouSearch.FindAll(); foreach (SearchResult oneResult in allOUS) { //comboBox1.Items.Add(oneResult.ToString()); comboBox1.Items.Add(oneResult.Properties["name"][0]); } I have been through and debugged everything i know, the searcher isn't picking up any results, hence why nothing is populated in the combo box.

  • Issue Querying LDAP DirectoryEntry in ASP.NET

    - by davemackey
    I have users login to my application via Active Directory and then pull from their AD information to garner information about that user like so: Dim ID as FormsIdentity = DirectCast(User.Identity, FormsIdentity) Dim ticket as FormsAuthenticationTicket = ID.Ticket Dim adDirectory as New DirectoryEntry("LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = ticket.Name.Substring(0, 5) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name") = adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Now, I want to be able to impersonate other users...so that I can "test" the application as them, so I added a textbox and a button to the page and when the button is clicked the text is assigned to a session variable like so: Session("impersonate_user") = TextBox1.Text When the page reloads I check to see if Session("impersonate_user") has a value other than "" and then attempt to query Active Directory using this session variable like so: If CStr(Session("impersonate_user")) <> "" Then Dim adDirectory as New DirectoryEntry(LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = CStr(Session("impersonate_user")) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name")= adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Else [use the actual ticket.name to get this info.] End If But this doesn't work. Instead, it throws an error on the first Session line stating, "DirectoryServicesCOMException was unhandled by user code There is no such object on the server." Why? I know I'm giving it a valid username! Is something strange happening in the casting of the session? The code is essentially the same between each method except that in one method rather than pulling from ticket.Name I pull from a session variable for the login I'll be looking up with AD.

  • LDAP socket keep-alive

    - by Dmitry Khalatov
    We are using OpenLDAP client library to conect to an LDAP server. The problem is that if there is no activity for some time, server (or firewall in the middle) drops TCP connection. Our current implementation of "keep-alive" just does search for baseDN from time to time - any better ideas ?

  • Can I use Google's Protocol buffers for processing LDAP requests in my LDAP server?

    - by Naga
    Hi, I need to process the incoming predefined ASN format data(coming from verity of clients that uses BER library to build it) in my application server. This is typically an LDAP server where every request will be in a predefined ASN format. Can i use Google's protocol buffers to process the requests in the server side? Will it help any way to improve performance of my servers request handling? Is it anyway reduce the number of malloc() calls that happens while processing ASN messages? Thanks, Naga

  • Storing LDAP Credentials

    - by Floetic
    What's the ideal way to store login and password for LDAP membership providers in the web.config? Having the login and password stored in the provider under connectionUsername/connectionPassword attributes does not go well with me because, I would want to encrypt the connection string later on. Don't have much experience with this, and was wondering if anyone had any best practices for this.

  • LDAP c++ API choice

    - by ypnos
    I would like to write my own LDAP client under Linux, specific to our local environment. Most probably I will use QT4 to provide a shiny frontend without much hassle. I found that there seems to be no standard C++ library for this. OpenLDAP provides a C API and there should also be a C++ API (experimental?) somewhere.. Do I need to use the C stuff or is there a C++ API out there worth of recommendation?
