Hello all, My apologies if this post belongs elsewhere, i'm new to the site. This issue appeared in the past month and has been plaguing the entire office slowly as their passwords are each expiring at different times. Windows Server 2008 R2 Standard with a mix of PC and Mac computers. Mac Books are configured to use mobile accounts for offline use. Recently clients started experiencing issues whenever the domain password expires. The Mac Book will prompt for the user to change their password. User is able to sign into their account and everything appears to be working correctly. However, if the Mac is locked or the users account is logged out, the Mac Book will prompt to change the password again during the next sign in. In the past, attempting to rest the password again will cause issues with the key chain and the domain credentials. Strangely enough, if the computer is restarted once again without attempting to change the password, the most recent credentials will work. This issue repeats itself over and over. The affected Mac Books are using a mix of High Sierra and Mojave. I'm sure there are many pieces of information i'm leaving out that are necessary to troubleshoot, I'm available to answer any questions. Thank you ahead of time!
