In CS3.x, the Microsoft Active directory LDAP integration did not work because when password was submitted on login page, the sharedFunctions.js file has md5hashedLogin set to true, which in turn would encrypt user password as MD5 and then submit to management core to verify. This auth method works fine for regular local auth and probably other LDAP servers but definitely not with MS LDAP as it does not support MD5 hashed passwords as input.
Is it still the case with CS4 or has anything changed? I wrote a fix for CS3.x and posted the solution on original/old bug tracker. I'm not certain if I need to do the same fix for 4.0 or we have this addressed. I looked at sharedFunctions.js file and it appears we are still doing the same thing. My AD login fails with invalid username and password - because CS4 submits my password as MD5 hash. As always, your feedback is appreciated. Thanks Ilya
