Hi! I'm trying to use change notifications as described in Microsoft article* using their example** with Active Directory Application Mode. The problem is that I do not receive any notifications: ldap_result() just blocks waiting for results and never releases. I specified LDAP_SCOPE_BASE to monitor just the object and I use a search filter of "(objectClass=*)". The object is certificationAuthority, immediate child of root of the naming context (which is my ADAM application partition). I just wanted to get notification when I attribute certificateRevocationList is updated (attribute uSNChanged is also changed at the same time), but I never receive notification. I'm using LDAP_AUTH_SIMPLE method and non-SSL port when binding to ADAM. I tried to authenticate using credentials of different ADAM users from different ADAM groups. From my experiments I found that it doesn't matter if ADAM user is member of Administrators or Users or Readers groups - ldap_result() waits indefinitely, never returns. If I bind anonymously, ldap_result() returns LDAP_RES_SEARCH_RESULT immediately. Could you please help with this issue? I wonder if change notifications mechanism described for AD is also supported in ADAM? Thanks in advance. * http://msdn2.microsoft.com/en-us/library/aa772153(VS.85).aspx ** http://msdn2.microsoft.com/en-us/library/ms676877(VS.85).aspx Best regards, Ivan
