SharePoint Server 2010 currently supports the following LDAP providers for importing user and group profile information into the SharePoint profile store:
But what if you need to import profile information from a different LDAP provider? Well, the good news is you can! In addition to directly supporting the three LDAP providers listed above, SharePoint Server 2010 also supports using a Lightweight Directory Interchange Format (LDIF) file to import user and group profile information from an LDAP provider to SharePoint Server.
LDIF files are typically used to exchange information with LDAP Directory System Agents (DSAs). However, you can also use an LDIF file to import profiles from your LDAP provider to SharePoint by using the SharePoint Server Synchronization Services Manager.
The following article explains how to do this in detail:

We've also provided a sample LDIF file that you can use for testing, along with the Config.xml file that you will need to use when setting up profile synchronization by using an LDIF file. These files can be downloaded here:
