52 service. Supported options are:
58 Disables keep-alive messages.
59 Keep-alives are packets sent at certain intervals to make sure that the
60 client is still there, even when it doesn't send any data.
65 Assume that clients connecting to this server will use some form of
66 Kerberos authentication. See the
75 For Kerberos 4 this means that the connections are encrypted. Kerberos
76 5 can negotiate encryption even without this option, but if it's
79 will deny unencrypted connections. This option implies
85 .\"When using old port-based authentication, the user's
87 .\"files are normally checked. This option disables this.
92 If the connecting client does not use any Kerberised authentication,
93 print a message that complains about this fact, and exit. This is
94 helpful if you want to move away from old port-based authentication.
98 When using the AFS filesystem, users' authentication tokens are put in
99 something called a PAG (Process Authentication Group). Multiple
100 processes can share a PAG, but normally each login session has its own
101 PAG. This option disables the
103 call, so all tokens will be put in the default (uid-based) PAG, making
104 it possible to share tokens between sessions. This is only useful in
105 peculiar environments, such as some batch systems.
