Domain Users can not change passwords

Domain Users can not change passwords

I can change my password as a domain admin, but normal domain users can not. They get the following error::

  Change Password Failed
 1. Incorrect Old Password
 2. Password chosen failed to meet any or all of the standards stated below:
   Minimum Password Length: A longer password is required.
   Password Complexity: Password should be a combination of alphabets & numerals.
   Minimum Password Age: When set, you cannot change password for specified time.
   Password History: Reuse of old password(s) prohibited.

I am definitely hitting the password complexity rules set in ManageEngine and in AD. If the domain user changes the password in Windows it works fine.

Is there a permission or a switch im forgetting to hit here?
