LDAP works for some but not all

[jehrbear]

I have CPS set up, and it's been working for years, all of a sudden all of my
users at one location cannot authenticate. The CSI file is fine, but it's had
to be replaced a few times. The users LDAP settings haven't changed.

The server is at siteA and all siteA users are fine. SiteB users cannot
authenticate to contribute, but they can log into VPN and choose a VPN
connection at siteA and they work just fine.

The Access Denied message is coming from CPS, and is not NTFS or other
security.

We've deleted an affected user and recreated the account in CPS and still no
luck.

Anyone Seen this issue before?

Without giving out the password or anything really secret, what are your LDAP setting setup as in the CPS side of things?

Problem resolved. After a few conversations with different teams, we found a
change that went in at the time this started and investigated what that change
was.

There is a new Wan optimization appliance that started being used between site
A and site B which apparently caused my problem. Once my connections where
excluded from this appliance, everything started working again as normal.

Just in time, I was planning to tear down and completely rebuild my server
today.
