[ActiveDir] Password Filter DLL and Trust Password

[Santhosh Sivarajan]

I am facing an issue after installing a custom password filter DLL. Password filter DLL is working fine for user password change.  But when I try to create a trust between NT and Windows 2003, it is not accepting any password combinations.  I disable the custom password filter DLL, and then it is started accepting the trust passwords.  We don�t have any code in the password filter DLL to check the trust password.  Is it a normal behavior?  I know trust is also calling LSA to check the password complexity.  Do I need to include trust password checking code in the password filter DLL?  Is there anything else I am missing in the Password Filter DLL? How about computer passwords?   Any input would be greatly appreciated!
