Hallo everyone, so now the Winsync from NT4 PDC -> FDS works fine (thanks to all) And now the next step gives me a problem. I do the Password sync without SSL connection (only one problem at a time). The setup should be correct: Windows Reg entry: (Default) (value not set) Cert Token "" Hostname "192.168.1.55" Install Path "C:\Program Files\Red....." Password "guessmypw" Password Field "userpassword" Port Number "389" Search Base "ou=People,dc=daheim,dc=weil" User Name "uid=useradmin,ou=Special Users,dc=daheim,dc=weil" User Name Field "ntuserdomainid" the bind user has the aci's to change all values in the user tree But I recive the following error at the PDC: "The description for event (105) in source (Password Synchronization Service) could not be found. It contains the following insertion string(s):." So in fact nothing happens :( At the FDS logs I don't see anything, so there seems no communication between ADS and FDS. The same as a question from RE: AD sync from Darjo Gregoric at Thu, 3 Nov 2005 Is there anything missing in the setup? Or is something wrong in the Password Sync Programm. And how should the log at the FDS look like (error log set to "Replication")? CU Hartmut
