This section describes the procedure to set the minimum length for a password.

Run the following procedure for each and every server in the topology:

1. Log in as admusr on the server.

   login: admusr
   Password: <current admin user password>

2. Check out the file system-auth and grep for variable ‘minlen’ in the file using the following command:

   
   $ sudo rcstool co /etc/pam.d/system-auth 
   $ grep minlen /etc/pam.d/system-auth

   • If a result is returned, then run the following command:

     $ sudo sed -i "/password.*requisite.*pam_cracklib.so/s/minlen[^ ]*/minlen=14/" /etc/pam.d/system-auth

   • If no result is returned, then run the following command:

     $ sudo sed -i "/password.*requisite.*pam_cracklib.so/s/$/ minlen=14/" /etc/pam.d/system-auth

3. Check in the file system-auth:

   $ sudo rcstool ci /etc/pam.d/system-auth
