client-encryption

This attribute specifies whether the defined file service accepts encrypted client passwords. It defaults to off. If you leave this attribute off, TAS expects clear-text passwords. If you set this attribute to on, TAS uses password files on its host. Passwords sent by clients receive encryption according to the method appropriate to that realm. You can add passwords to the TotalNET password database using tnpasswd. TAS ignores this attribute if you define authent-proxy.

Usage:

tnservice -M -r realm -s service -a client-encryption={on|off}
