Sebastian, Thanks for the reply. I do a tcpdump in the ldap traffic between the Domain Controller and Openmeetings.
For both (previous and 1.8) versions I see to requests: 1st is the Bind to Authenticate the user. It sends the username and password and receives a Bind Response with Status = Success 2nd is a Search. It sends the Base Search and the sAMAccountName correct and receives a search Result Done with Status = Success but MatchedDN: NULL The processes seems to be exact the same on both versions. But just 1.8 give me the error. Regards, João Vitor Arruda -- You received this message because you are subscribed to the Google Groups "OpenMeetings User" group.
