Difference between deleting approver set up and disabling.

Disabling an approver : The user will not be able to access the temporary suspension screen itself.

Deleting an approver : The user will be recreated for both Single Sign On and Basic Authentication, so no need to pay attention to this.

*Never disable if "you want only to remove the user from approvers, but want to let him access the suspension screen as a general user".
