There is plan, but nothing for sure. I'm thinking about abstracting authentification so you can use aC user database, LDAP, user database of other application or anything else.
Thats just a plan, I can't tell you when it will be implemented.
Same here, another vote for ldap authentication. I am running off a dreamhost installation which allows me to run the program without having to ram it through IT, but limits how many users I can reasonably add to the system manually. Cheers
Abstracting authetication is one of the things that will be added to 0.8 so you can create your own authentication sources - will it be some existing database, web service, LDAP or whatever, you will be able to make it. activeCollab will ship with default source (current implementation) and if you need something specific just use or write a different plugin.
It's not too hard to hack the auth. Right now in aC i've changed a bit of the a uth so it just checks the username in aC, but the password and username get tossed to our internal intranet login app that then tosses it to an ldap, then i just read the callback within aC.
Thanks,
