We're a small education institution that supports a number of Macs for faculty members. With the recent upgrade to 10.7.4 we've noticed some very odd issues. We configure a local admin account, let's call it "professor". All PC's and Mac's have this local admin account configured for all support staff members have a local login. For reasons I have no control over, we also have a domain account called "professor" that does not have administrative rights. This is used by a small number of people Mac's are bound to the AD. With the install of 10.7, we've noticed that when we are plugged into the network and type in the "professor" username and local admin account password, we get logged into the network "professor" account and do not have any rights. Any ideas, or any other information I can provide that would help resolve this?
