Cannot login to Application Manager plugin for OpManager

Hello,
I cannot log to my ApplicationManager OpManager plugin page.
The only enabled user seems to be the admin one.

Every user we tried (local or Active Directory) is not valid.
We have all the time a login page with "Invalid username and/or password."

It seems that ApplicationManager plugin doesn't access to the user configuration of OpManager
for all users but the admin one.

How can we troubleshoot this problem?
