Thread:Extension talk:LDAP Authentication/Incorrect login details freezes wiki/reply (6)

The current stable release is 1.2a, but the current SVN version is 1.2b. I haven't released a stable in a while, but the SVN version is actually quite stable. I have a few more things to add before I actually do a release.

As for your problem... I haven't had any other reports of this type of problem, and I've never encountered it myself. I'm unwilling to put a php 5.3 only feature into the extension to solve this. I'm not exactly sure what your issue is, but it seems to be related to your web server, or your LDAP server. I'd guess it is the web server out of the two.
