Changing Active Directory User ID, still passes old ID
Posted on 2014-12-13
I have been changing a number of our user ID's in Active Directory. I am changing both the Pre Windows 2000, and the AD users Domain\old and firstname.lastname@example.org to Domain\new and email@example.com.
The user is able to login and everything works, except for a few things.
We have a number of products that will accept a passthru AD authentication from the workstation. So if they goto a particular internal web site, or some other product, their credentials can be passed through.
What we are finding, for some strange reason, even though we have changed their username from Domain\old to Domain\new, when we wireshark it, we are seeing the domain\old being passed to the services. They are logged in as domain\new.
I have cleared cached credentials. I even made them login into a brand new computer that they have never been logged into before, and we are seeing that domain\old is still being passed. At this point I am a bit confused. I can not figure out where it is coming from or where it is being passed from.
