Plesk Automation (PA) 11.5 node is registered in Odin Business Automation Standard (OBAS) 4.5 and several PA subscription have been provisioned.
It is not possible to manage a PA subscription upon login to Customer Panel from OBAS PCC (Top > Account Director > Customer Manager > Customers > %customer% > Log in to CP) or directly (https://%pbas_node%/cp). PA login page appears on the Websites tab.
The data about customer account and admin user is not synchronized between OBAS and PA. It can occur if an admin user (staff member) known to OBAS was removed in PA and a new admin user was created for an account in PA with a different login name. That results in OBAS inability to log the user into PA Control Panel, for the login information stored in OBAS becomes outdated.
Since the issue requires complex manipulations with the database, it is recommended to contact Odin Technical Support for assistance.
