Hi all,
This is my first post here and I hope I am giving all of the necessary information. First of, I am talking about:
21 in iMac, 2010
Running El Capitan (OS X v. 10.11.2)
4 gb RAM
500 GB Hard Drive
Windows AD Server running Server 2008
No OS X Server integration at this time. Only using AD Utility.
We have been doing this for about 5 years with little hoops and bumps to get through. Login errors have come down to issues with wi-fi, network connectivity, Time Errors, and all of those were ironed out about 2 years ago and things have been running smoothly ever since.
We were running on OS X 10.9 (Maverick) until I recently re-did the image. About three months before re-doing the image, I had one student user who was getting the following error when logging in on the Macs:
You are unable to login to the user account "xxxxxx (insert username here)" at this time. Logging in to the account failed because an error occurred.
Mind you, this was one user, and rather than look into it further, I knew it was time to re-image and upgrade anyway so I focused on that. The new image was put on, and the user with the error before was now able to login.
However, about 2 weeks after the lab had been imaged, another user in the same OU had been getting the same error. Not only would he get that error, but everyone who logged in after he got the error would get the same error until the machine was rebooted (only on that machine, they could login elsewhere fine). Also, this user never has any issue with logging in to a windows machine.
After checking the network folder permissions, deleting his home folder, and trying to delete any residual information on his network drive, I still was getting the same issue. The next step I tried was to dele his account and then added him back with the same credentials. However, his network folder was completely new (I backed it up, of course, but didn't put the backed up info in his folder yet). Now, all he gets when trying to login to the Mac's is the typical "shake" that happens when a username or password is incorrect. I don't even get the error anymore.
I am now looking to see if anyone has any suggestions as I am at a loss and confused as to why this is only happening with one student, not every student or user login.
Thanks!
