When EFT Server connects to an LDAP server, the LDAP server usually replies with the list of users in the AD server. Occasionally the LDAP server returns a list with 0 users, causing EFT Server to lose all of its user/group associations. If the LDAP server returns an empty list of users, this registry key causes EFT Server to expect the list to come back empty, ignores the results from the query, and keeps the user/group associations that it has.
To activate this feature, create the following keys:
[HKEY_LOCAL_MACHINE\SOFTWARE\GlobalSCAPE Inc.\EFT Server 4.0]
"UserDatabaseSynchronizationMode"=dword:00000002
0 = normal
1 = log auth provider synchronization to Windows Event log, but otherwise normal
2 = log auth provider synchronization and do not delete users
[HKEY_LOCAL_MACHINE\SOFTWARE\GlobalSCAPE Inc.\EFT Server 4.0]
"IgnoreZeroUsersResult"=dword:00000001
0 = normal
1 = If zero users received, abort and do not honor sync attempt. Event is logged to the Windows Application log.
