Active Directory actually creates users “temporarily” and then deletes the entries if the password does not meet the password policy requirements. Consequently, the Active Directory Connector sees this temporary ADD and creates users on the Directory Server side. The users will not have a password in Directory Server, so no one will be able to log in as the user. In addition, these entries will not be linked to a valid entry in Active Directory. If deletions are synchronized from Active Directory to Directory Server, then the temporarily created users will be deleted automatically.
Users are created without a password on Directory Server. Directory Server does not enforce the password policy for user creations unless the entries contain a password.
There are several ways to recover from this situation. The preferred method is to synchronize deletions from Active Directory to Directory Server. Alternatively, you can remove the user from Directory Server and then add them to Active Directory with a valid password for the Active Directory password policies. This method ensures that the users are created on Directory Server and linked properly. Users on Directory Server will have their password invalidated when they log into Active Directory for the first time and change their passwords.
If you do not delete the user from Directory Server, and then try to add the Active Directory user again with a new password, the ADD to Directory Server will fail because the user already exists on Directory Server. The entries will not be linked together and you will have to run a idsync resync command to link the two separate accounts.
If you run the idsync resync command, you must be sure to reset the passwords for the accounts on Active Directory that were linked to entries on Directory Server. Resetting the passwords invalidates those passwords on Directory Server, which then forces on-demand synchronization to update the Directory Server password the next time the user authenticates to Directory Server with their new Active Directory password.
