Answer 1

You can achieve this by fetching all groups that contain the user in their member attribute, or better the user's LDAP path (distinguishedName). Here's a simple procedure doing that job.

CREATE PROCEDURE dbo.GetLdapUserGroups
(
    @LdapUsername NVARCHAR(256)
)
AS
BEGIN
    DECLARE @Query NVARCHAR(1024), @Path NVARCHAR(1024)

    SET @Query = '
        SELECT @Path = distinguishedName
        FROM OPENQUERY(ADSI, ''
            SELECT distinguishedName 
            FROM ''''LDAP://DC=domain,DC=com''''
            WHERE 
                objectClass = ''''user'''' AND
                sAMAccountName = ''''' + @LdapUsername + '''''
        '')
    '
    EXEC SP_EXECUTESQL @Query, N'@Path NVARCHAR(1024) OUTPUT', @Path = @Path OUTPUT 

    SET @Query = '
        SELECT name AS LdapGroup 
        FROM OPENQUERY(ADSI,''
            SELECT name 
            FROM ''''LDAP://DC=domain,DC=com''''
            WHERE 
                objectClass=''''group'''' AND
                member=''''' + @Path + '''''
        '')
        ORDER BY name
    '
    EXEC SP_EXECUTESQL @Query

END
