  • What Are Some Good Open Source Alternatives to Active Directory?

    - by Laz
    I'm looking for a good open-source alternative to active directory that can handle: Authorization/Authentication Group Policy Replication and Trust Monitoring In addition, are there any consolidated systems out there that handle these responsibilities? Edit: Since a lot have asked for more details, I am trying to offer a service setting up an infrastructure for organizations, hardware/software setups, right now I am looking at a Linux stack, both desktops and servers, however a hybrid stack is possible, and I am investigating alternatives.

I am interested to hear how you would approach evaluating and consolidating a network in a situation like this where you are walking in cold? What are some of your go-to techniques?

  • Disadvantages of not having a swap partition

    - by Bo Tian
    I recently installed Ubuntu 10.04 on my laptop. Due to space constraint of the SSD, I did not set a swap partition for the OS, and I have 1.5GB of RAM. There's a warning during installation, but I think it's not a big deal since everything went smoothly. For the long term, would there be any drawbacks of not having a swap partition?

  • Setting a non-standard proxy

    - by Julio Guerra
    I am behind a proxy which requires users to login during the first connection with a username and password with a HTML form. Thus, it is not handled with usual http://username:[email protected] and any attempt to access the internet from this setting falls into the login form. How could I automatically login to the proxy? In linux, what manages proxy stuffs when a command tries to access the internet? Thank you.
