I'm starting to see an issue with our Mac's (bond to AD) will lose their connection to AD. Here are the symptoms that I notice when I start having odd issues:
My wireless will not connect. (We use Computer Authentication, which requires your Mac to be bond to our AD)
My Domain admin account will no longer be able to "unlock" preferences or do any admin task.
If I try to use dscl to browse AD, I'm able to do a "ls" at the top level and see "/Active Directory" and then cd (change directory) to /Active Directory. Next I do "ls" again and see our domain LPCDOMAIN1, but I can't change directory to it. It will give me an error message. (sorry I don't have that wrote down)
Troubleshooting step:
When I check the "Login Options" under Uesr&Groups, it show that I'm joined to AD and will list my domain name and the green light.
I'm able to find my computer name in AD, when searching with "MS Active Directory Users and Computers" tool.
My Search Path will show /Local/Default and /Active Directory
I'm able to ping my DC by IP and name.
It acts like the mac is bond to AD, but can't talk to it.
Work around:
Unbind from AD
Rebind to AD
Reboot
I'm wondering if anyone has seen something like this. This has only happened on a few Macs and all of them were running 10.10.2.
Most of our Mac's are still on 10.9.5 and never experienced this issue.
