Problem to Import Requesters from Active Directory

Problem to Import Requesters from Active Directory

Hi,
 
I got a problem with the import requesters from Active Directory. Everything have always worked but now the import process stays at 0%. I can log on to service desk trough Active Directory without problem but cannot import new requesters...
 
Here are the errors shown in serverout0.txt :
Users List : LDAP Enumeration Failure.  (0x80072030)
[SEVERE]|[79]|: Exception while fetching User List for OU
[com.adventnet.sym.adsm.common.server.ADHandler]|[SEVERE]|[79]|: Error when importing.  SO RETURNING...|com.adventnet.servicedesk.ServiceDeskException
[SEVERE]|[79]|: Exception while getting user credentials in getUserId. Assuming Non-Login view.
 
I have to say that It was already working fine for a few years and i just recently saw that it was not working anymore...
Service Desk version : 8.0.0 Build 8016
 
Thank's
Simon
