Limiting Concurrent users in SAP Portal 7.5 -- Issue after configurations

[Former Member]

Dear Experts,

We have made follwing configurations in development portal (7.5) to restrict the number of concurrent users.

MaxUsersCount = 2 (NWA)

SessionExpirationPeriod = 10000000 (2.78 hours) (NWA)Global_app_config/maxSessions = 2 (configtool)Global_app_config/session_config/sessionTimeout = 166.67 (2.78 hours)

(configtool)

We can login with 2 concurrent test users but we are getting blank page while trying to login with 3rd user simultaneously as soon as we enter the credentials in standard login page. It should provide the error message "Logon limit reached. Try again later" instead.

Please find the log extract for the same and please help me out.
