Use Non-Domain Admin account?

I have installed ADSelfService Plus 4.5 on a test system for evaluation. I've installed it as a service, and provided a username and password of a user that was a member of the Account Operators builtin domain group. The status for the domain initially said "The user/system has no admin privilege", but later when I looked again it said "Success". However, if I go in as an enrolled user to Reset Password, answer my security questions and what not and enter a new password, I get an error that says "Administrator credentials in application do not match with the one found in Active Directory".

From what I can tell, the software is requiring that the user you provide for ADSelfService to log into AD with be a member of Domain Admins. That seems like complete overkill to me. Can this behavior be changed so I can use a role account from Account Operators?
