Code Issues Proposed changes

Fix users not able to change their own password/key

Browse Source 
Users were not able to update their own password/key
with the update operation resulting in 403 (HTTPForbidden).

EXAMPLES:
Command to update password/key of regular user:
gswauth-add-user -U account1:user1 -K old_pass account1 user1 new_pass

Command to update password/key of account admin:
gswauth-add-user -U account1:admin -K old_pass -a account1 admin new_pass

Command to update password/key of reseller_admin:
gswauth-add-user -U account1:radmin -K old_pass -r account1 radmin new_pass
