Does UBB support LDAP authorization for user accounts?

I did a search for LDAP but nothing was found...

At this time, we do not. It's something we've had on our todo list for quite some time, but always gets pushed back because the demand for it has been fairly minimal.

Though it's probably quite a bit of work, please do consider putting this feature back on your agenda. It would be a selling point. In my case, I need an off-the-shelf solution (minimal customisation) for my business unit. UBB.threads is very attractive but for this one missing feature.

The (rather large) organization I work for has the typical "single signon" mantra going.

Thanks for the quick reply!
