The article Manage Active Directory synchronization in Project Server 2007 will contain the following updated information when it appears in the Project Server 2007 TechCenter next week.
User Synchronization Issues
Under certain circumstances, synchronizing Project Server users and workspaces with Active Directory can cause a “deadlock” situation in which all users are locked out of a PWA site or the respective workspaces. This causes user synchronization jobs to fail and site permissions to synchronize partially or not at all. Users may not be able to log on to PWA or their workspaces. A deadlock can occur if the user synchronization process is taking too long to complete. This is due to the synchronization job iterating through many users and workspaces, for example, when large membership changes are being made. A synchronization job remaining in the queue a long time increases the possibility of other jobs starting inadvertently, which can also cause a deadlock.
To reduce the chance of a deadlock, you can do the following:
