Well, the issue remains, how you lookup the unique id. You need to do it via
username and/or parts of the sip message. You can load avps or do any other
operations using unique ID in openser, for some time now, that is not an
issue. Apart of that, there are other values that are used in the config or
modules, that may, or may not require case insensitive comparison and one
cannot assign unique id for each.
What I consider a proper behaviour is
1) getting usernames into a normalized string form (%-escapes, upper/lower-case, local
naming policies, internatilization, ettc., etc.)
- failure not to do so is likely to result in mismatch
Thus, regardless if your setup is based on UUIDs or [EMAIL PROTECTED] we
have to find a way to make step 1.
What about having AVP-translations for converting to lower/upper case?

2) translation of normaized names into unambiguous unique ids
- failure to do is is likely to caused difficulties with aliases (domain
aliases,
user aliases, combination of both)
3) doing subsequent operations using ids.
See above inline for what happens when you do it other ways. In any case
that's how unambiguous behaviour shall be achieved in a "water-proof" way.
So, I do not see any fundamental error here, given the subject of the
discussion.
looking up user data by his username as opposed to by id is just very poor idea,
let's face it. (those familiar with unix may find too that usernames are used
as input/output user-interface thing, but the OS actually operates over numbers)
The funny part is that getting things right is apparently not a big deal in this
case, but getting it wrong can cause big headaches.
I am not sure though what of it is coding and what of it is configuration thing in
openser, I'm sure some will know.
