I cannot login to Plesk 10.4 from OBAS 4.5 using "Log in to Parallels Plesk Panel". When I click the button from Provider's panel Plesk login page is opened. But clients are still able to login to CP for managing their subscriptions.
When the "Log in to Parallels Plesk Control Panel" button is clicked on, OBAS generates login session for Plesk node with the API request:
[2014/01/03 18:56:10] [DEBUG]  [HSPC::MT::Plesk::PleskGate::__send_request_to_agent] Sending packet to 22.214.171.124 : 8443 : /enterprise/control/agent.php [2014/01/03 18:56:10] [DEBUG]  [HSPC::MT::Plesk::PleskGate::__send_request_to_agent] Final Packet=<packet version="126.96.36.199"><server><create_session><login>admin</login><data> <user_ip>OTEuMjA0LjI1LjQ=</user_ip> <source_server></source_server> <locale_id></locale_id> </data></create_session></server></packet> ...

The session is initiated on Plesk side, it is shown in Plesk panel on page
Tools & Settings > Active Sessions. After that OBAS sends the following link to Plesk node for authorization:
But authorization using this link fails on Plesk side and so the login page is shown.
NOTE: the issue does not affect clients login - customers are able to login to Plesk node for managing their Plesk subscriptions.
The problem has been fixed on Plesk side in versions 11.x.
Upgrade Plesk to version 11.x.
