Forms authentication and Profile Synchronization using LDAP.

Hello everybody,

I have recently migrated a SharePoint 2007 Web Application to 2010, I've configured it for using Claims Authentication because our client wants to log in his users using FBA with their Active Directory username and password. For that purpose I have used the LdapMembershipProvider and LdapRoleProvider.

Now, my first problem is the display name in the people picker; I mean, in another Web Applications configured for using just Windows Authentication the display name is correct, but for this one that is using FBA the display name is just the username, not his real name. Somebody mentioned that using the SharePoint commands for changing the display name would be enough but doing that for hundred of users is not an option. Also, I don't think that the client likes to wait until some developer run that command.

I remember that this problem could be solved on SharePoint 2007 using the profile importation with theLDAP Directory connection. Now it comes my second problem because after configuring the Profile Service Application I note that theLDAP Directory connection is not supported by SharePoint 2010 (Microsoft doesn't mention why) and I could not import the profiles. Another blog post mentioned that using LDIF files I could do and I'm still trying to do work that because I cannot restart the Domain Controller in order to get the LDIF file.

In the mean time I created a Profile manually for an FBA user in order to see if it fixed the People picker Display Name, for my surprise it didn't. The people picker is still showing just the username, for the FBA logged in users too. If I go to the "My Site" site collection it is worst because the display name is in the claims authentication way (i:0#.f|membershipprovider|username), but if I go to the "My Documents" section in the "My Site" site collection, It's showing me the display name as expected. this is my third problem .

So, here are my questions:

1. How can I do for displaying the real name in the people picker?
2. Is there another option for getting the LDIF file without restarting the domain controller?
3. Is there any way to be consistent in the way that SharePoint is showing the Display name in its pages?
