When attempting to sign in to the Customer Portal Administrator page, I receive the following error:

Invalid Session
You have reached your session limit or encountered a login error. Click here to log out and sign in again.

Customer Portal Versions 3.11 and greater allow SSO access to the Customer Portal Administration page. Because of this, you may hit concurrency issues with SSO users.

Use 'Logged in Staff Accounts' report id 13006 or a variant to determine the number of SSO Administrator sessions.

After reviewing the output from the report, consider updating the following configuration verbs as needed:

CONCURRENT_ADMIN_LOGINS_LIMIT_CP 

SESSION_CP_ADMIN_LIMIT
