The administration server is installed when you first install SuiteSpot server. For remote logon, it authenticates by validating the password prompt input with the administration server password file. This password file is kept in a local directory within the SuiteSpot server. The SuiteSpot superuser password file is located at the following path:

http://www.example.com/admin-serv/config/admpw

The admpwd file is in the ‘user:password’ format, with an encrypted password field which can potentially be compromised by a brute force attack. This user has full access to all features in the administration server and sees all forms in the administration server except the Users & Groups forms since these require in a valid account in an LDAP server such as Netscape Directory Server.

The Netscape-Enterprise manual page on Administration Server specifies that it is recommended that you write-protect the admpwd file since this is not done by default. This leaves a security hole which allows third party unauthorized users to potentially gain full access to the administration server console.

The administration server will reside on the port which you decided upon installing SuiteSpot.

Solution:
1. Set write-protect permissions on the admpw file located at <server_root>/admin-serv/config/admpw
2. Shut down the administration server in the following ways:
 A. Go to Server Manager and choose Admin Preferences|Shutdown. Click ‘Shut down the Administration Server’.
 B. On a UNIX system:
  To stop the administration server, go to your server root and type ‘./stop-admin’.
  To start or restart the server, type ‘./start-admin’ and ‘./restart-admin’ respectively.
 C. On NT:
  To stop the administration server, go to Control Panel|Services. Select the ‘Netscape Administration Server’ and click Stop. To restart it, click Start.’
