56 Disables keep-alive messages.
57 Keep-alives are packets sent at certain intervals to make sure that the
58 client is still there, even when it doesn't send any data.
63 Assume that clients connecting to this server will use some form of
64 Kerberos authentication. See the
73 For Kerberos 4 this means that the connections are encrypted. Kerberos
74 5 can negotiate encryption even without this option, but if it's
77 will deny unencrypted connections. This option implies
83 .\"When using old port-based authentication, the user's
85 .\"files are normally checked. This option disables this.
90 If the connecting client does not use any Kerberised authentication,
91 print a message that complains about this fact, and exit. This is
92 helpful if you want to move away from old port-based authentication.
96 When using the AFS filesystem, users' authentication tokens are put in
97 something called a PAG (Process Authentication Group). Multiple
98 processes can share a PAG, but normally each login session has its own
99 PAG. This option disables the
101 call, so all tokens will be put in the default (uid-based) PAG, making
102 it possible to share tokens between sessions. This is only useful in
103 peculiar environments, such as some batch systems.
