Sharepoint user details not visible to other users -

I am managing a SharePoint site which uses form based authentication. We have several generic lists, document libraries, and active working lists, which users can create and delete. Users can use people's pickers to select / search for all people, but users can not see other user names, email addresses, etc. in the display list or people's picker. If I log in as a site collection administrator, then I can see all the details. So I know that the data is available.

The updated details (non-administrator) SharePoint users can not see other user information on this issue. Example: User A was assigned a task for User B A new job is made from User A and people use beaker to find userb user. User B. Only the login name "BNN" and any information about User B is not visible or searchable, once user B has been assigned the task within the people's picker, User A no longer sees the name in the work list - even if the user A. It is made by no modification, created by, or assigned to owner field data is visible to non admin users.

1. Extranet is configured to use site form authentication
2. Intranet Windows based authentication
3. Users of both intranets and extranets
4. The site uses SSRS integration
5. SharePoint WSS class

- verbose logging it looks like SharePoint for sure At present, the user's entry is only asking the SQL Server for the information of the user after activating:

select Top 6 / Lots-of-Column / UserData from within Join the document on the merge (1 = 1 and UserData as t1 [tp_RowOrdinal] = 0 and t1.SiteId. = UserData.tp_SiteId and t1.SiteId = @ L2 and t1.DirName = UserData.tp_DirName and t1.LeafName = Include AllUserData as UserData.tp_LeafName and t1.Level = UserData.tp_Level and T.IsCurrentVersion = 1 and (1 = 1)) on Left External (UserData. [Tp_Author] = t2 T2. [Tp_ID] and UserData. [Tp_RowOrdinal] = 0 and t2. [Tp_RowOrdinal] = 0 and ((t2.tp_IsCurrent = 1)) and t2 [Tp_CalculatedVersion] = 0 and t2. [Tp_DeleteTransactionId] = 0x and t2.tp_ListId = @ L3 and UserData.tp_ListId = @ L4 and t2. [Tp_Author] = 162 / * This user is currently logged in * /) Where (UserData.tp_IsCurrent = 1) and UserData.tp_SiteId = @ L2 and (UserData.tp_DirName =@DN) and 0 UserData.tp_RowOrdinal = and (Order by userData) or (UserData. [Datetime1] is zero) or (UserData. [Datetime1]> = @ L5DTP)) and t1.SiteId =@L2 and (t1.DirName =@DN). [Tp_Modified] Description, UserData. [Tp_id] ASC

Then, any ideas would be apprecia TED. After working "impossible" through "text" itemprop = "text">

To view the user list, I navigate to: Site Activities> Site Settings> People and Groups> Settings> List Settings> Advanced Settings> and found that users only see their own user items .. I hope Being able to help it out in someone else Area was determined to <. / P>
