So my problem seems to be getting worse.
At first it was just a few LDAP users that were experiencing this issue, now more users seem to be getting this error AND as of this morning a local user has this problem too.
Here are the details and some background information of specifically what I am seeing:
On Monday October 29, 2012 I upgraded our TEM infrastructure from 8.2.1093.0 to 8.2.1312.0. The first LDAP user experienced the “Communication Link Failure” error Friday November 2, 2012. The second LDAP user I am aware of experienced this issue Monday November 5, 2012. As of this morning, Tuesday November 3, 2012, more LDAP users are starting to experience the issue along with one Local user.
I am one of the users affected as of this morning. Here is what I have noticed with the logins:
I was able to login this morning with my userid in all lowercase: a-jm15
A few hours later I started noticing console errors so I logged out and attempted to log back in. When logging back in I experienced the error above.
I then tried my userid with all uppercase: A-JM15
This worked. So I decided to log back out and try another combination.
I then tried all the following which were all successful: A-jm15, a-Jm15, a-jM15, A-jM15, a-JM15
So it seems any case combination ID except for the one experiencing the problem originally is working. Why would my lowercase ID start giving me the “Communication Link Failure” error? I also tried all the random case combinations with the local user and they all work except for the ID that originally received the error.
