Usersync service is not running as per default schedule of 120 minutes

[shubhampandey16]

As per my understanding, value of SYNC_INTERVAL parameter translates into how often Usersync service should be running to sync users/groups from LDAP. In my setup, I havet specified a value to this parameter but as per the documentation, default value is 120 minutes.
But Usersync service is not picking up automatically after 2hours.
