Earlier this week we were greeted with this awesome message:

It’s so descriptive we knew exactly where to start! Okay, yeah, not really. Sarcasm aside, you’d think the culprit would be SSO. I began checking the two SSO servers we have in an HA configuration and they appeared fine. What’s even more strange is the fat clients were all authenticating fine. I started checking logs on the SSO servers and saw several things similar to this:

2015-08-25 23:20:49,538 INFO [ActiveDirectoryProvider] Failed to find user snip@snipPrincipal id not found: {Name: snip, Domain: snip} via ldap search
2015-08-26 00:29:37.709:t@21945040:ERROR: ldap simple bind failed. Error(4294967295)

So I assumed it was SSO again, maybe related to the domain we auth against.

Great! So now what?
