null-passwd-login

This attribute determines whether users with "null" UNIX passwords can connect to the host through TAS using the defined file service. This attribute defaults to off, which denies users without passwords access to the server. You can use this attribute to provide access through a null password guest account. This attribute only applies to services with client-encryption set to off, and it does not work for share mode file services in the LM-NT-OS/2 realm. The file service checks this attribute before sending the password to an authentication proxy server, if you define authent-proxy.

Usage:

tnservice -M -r realm -s service -a null-passwd-login={on|off}
