Thanks for your reply!
I wouldn't know how that would've happened. We're authenticating
against Postgresql and AFAICT nothing changed in the DB, username-wise
(we're using "name at domain.example" style user accounts, if that
matters).

During the (RPM) upgrade, the config files were (as expected)
temporarily reset to the distribution defaults and I had to merge our
settings (DB credentials etc.) back into the new configs. (JFYI and
probably unrelated: I noticed that for users that had logged into
Horde during that config merge time, all their shared calendar
subscriptions were lost, but this only affected a handful of users.)

I can't exclude the possibility that we were/are using ancient config
settings, but the diff didn't look like it. I can't find any config
related to case/upper/lower.

What further info can I provide to narrow down the cause of the
problem? Should I attach any (sanitized) configs?
