 ===== LDAP Integration =====
-ILRI uses an Active Directory server for user authentication, which is primarily used for Exchange e-mail services.  Active Directory is Microsoft's version of LDAP with a little special sauce.  Currently users have an Active Directory username and password for their Windows-centric single sign on and e-mail, and then they have a separate account for use with the HPC.  There exists functionality in Linux to look at Active Directory for user authentication.
+ILRI uses an Active Directory server for user authentication, which is primarily used for Exchange e-mail services.  Active Directory is Microsoft's proprietary version of LDAP with a little extra special sauce.  Currently users have an Active Directory username and password for their Windows-centric single sign on and e-mail, and then they have a separate account for use with the HPC.  There exists functionality in Linux to look at Active Directory for user authentication.
-<note warning>ILRI's Active Directory servers are configured to [[http://support.microsoft.com/kb/326690|disallow anonymous binds]] so we need to use a special account account which is allowed to perform queries.  Robert Okal has given me an account to perform queries, the name is ''bioinfohpc''</note>

+According to the web this error means the user does not exist.  Either I've specified the user's distinguished name incorrectly, or the account is not configured with the proper permissions to bind.

+<note warning>This no longer works! It relied on anonymous access to the AD server, but ILRI's Active Directory servers are configured to [[http://support.microsoft.com/kb/326690|disallow anonymous binds]].  These notes have been left here for reference only!</note>
 This was working once, using a //slightly// customized PAM module, but broken when IT services disabled anonymous binding.  In order to use the module several steps are needed.  Download the module source and edit the code to point to the correct server, then compile it as shown below:
