I have done some testing...
MDAEMON is easy to setup to talk to your Domain Controller.
You do Not need the LDAP tool if you already have a DC.
We set up a test MDAEMON server, imported the user from The IMPORT option in MDAEMON, and found that it works great.
It changes the users password to "\\servername"
When we changed the password in Active directory, MDAEMON authenticated fine. The trick is to have all your users set to have that as their password in MDAEMON. Now.. you may want to set password changes to NO to keep them from screwing things up.
If You disable a User in Active Dir, they cannot connect to their email beacuse their password cant authenticate. You just have to manaully setup each user (IMPORT) but thats it.
As for LDAP and CF....
Tried the Custom Tag ADAuthen from the new and "improved" Macromedia/Allaire site.
I set up a form that asked the Username and Password... It took several seconds and then reported the user was not valid. I think that tag timed out and returned the null value, so it never reaaly worked.
I am taking a break from it now, hoping someone out there has an answer... I will keep at it and let you know.
Please let me know if you hear anything!
Thanks
