LDAP and user name length limit

[tniemi]

Hello,

I am running OpenMeetings successfully with OpenLDAP enabled
authentication. I have a problem with users which have less than 4
character long user name. Following error for these users is
displayed:

4 or more charaters; capitalization matters!

The log shows following:

Is it possible to change this limit somewhere?

I'm afraid this limitation has something to do with SIP support.

Anyone come up with a fix for this?  What if you don't need or care about SIP support?

[seba....@gmail.com]

I think the username lenght is hardcoded at the moment and indeed it had sth todo with the SIP Gateway (but that needed 6 chars in lenght minimum).

If you could add an Issue to *add config param in the Administration to configure min username length*, I'll integrate that into the next release.
