CA Business Service Insight AD integration is enabled via the UI Administration -> Site Setting -> Advanced -> System
An error must have been made during the configuration and login to the UI is no longer possible.
How can the AD integration be disabled?
CA Business Service Insight 8.3.5 and 9.x
The configuration settings are stored in the database table T_SYSTEM_CONFIGURATIONS.
To revert the change directly, you can connect to the Oracle BSI database run the following:
update T_SYSTEM_CONFIGURATIONS set sys_config_value='N' where sys_config_name like 'is_ad_authentication_enabled';
Then on the BSI Web server, run the IISRESET command.
This will revert back the BSI logins to default and make the UI accessible once again.
