Performing different SAP logon check while connecting to HANA
When a user logins to the HANA system, the following steps are performed −
Step 1
The system authenticates the user using the configured mechanism.
Example − When User name/password authentication is being enforced, the provided user name and password are verified.
Step 2
The system verifies that the user's account is within its validity period.
In the system view USERS, the columns VALID_FROM and VALID_UNTIL must contain effective values for the user in question.
However, this is an optional parameter that a user administrator can set during user provisioning.
Step 3
The next step is system verifies that the user's account is active.
This can be performed by checking the value in the system view “USERS”, the column IS_DEACTIVATED must contain the value FALSE for the user in question.
A user account may be deactivated explicitly by a system administrator or by the system.
Example − due to too many invalid logon attempts.
When the above checks are successful, it allows users to login to SAP HANA system.
