57 d93fca6a 2005-02-11 devnull .I Authdial
58 d93fca6a 2005-02-11 devnull dials an authentication server over the
59 d93fca6a 2005-02-11 devnull network rooted at
60 d93fca6a 2005-02-11 devnull .IR net ,
62 d93fca6a 2005-02-11 devnull .BR /net .
63 d93fca6a 2005-02-11 devnull The authentication domain,
65 d93fca6a 2005-02-11 devnull specifies which server to call.
68 d93fca6a 2005-02-11 devnull is non-nil,
69 d93fca6a 2005-02-11 devnull the network database
71 d32deab1 2020-08-16 rsc .MR ndb (1) )
72 d93fca6a 2005-02-11 devnull is queried for an entry which contains
73 d93fca6a 2005-02-11 devnull .B authdom=\fIad\fP
75 d93fca6a 2005-02-11 devnull .BR dom=\fIad\fP ,
76 d93fca6a 2005-02-11 devnull the former having precedence,
77 d93fca6a 2005-02-11 devnull and which also contains an
79 d93fca6a 2005-02-11 devnull attribute.
80 d93fca6a 2005-02-11 devnull The string dialed is then
81 d93fca6a 2005-02-11 devnull .I netroot\fP!\fIserver\fP!ticket
83 d93fca6a 2005-02-11 devnull .I server
84 d93fca6a 2005-02-11 devnull is the value of the
86 d93fca6a 2005-02-11 devnull attribute.
87 d93fca6a 2005-02-11 devnull If no entry is found, the error string is
88 d93fca6a 2005-02-11 devnull set to ``no authentication server found''
89 d93fca6a 2005-02-11 devnull and -1 is returned.
91 d93fca6a 2005-02-11 devnull .I authdom
92 d93fca6a 2005-02-11 devnull is nil, the string
93 d93fca6a 2005-02-11 devnull .IB netroot !$auth! ticket
94 d93fca6a 2005-02-11 devnull is used to make the call.
96 d93fca6a 2005-02-11 devnull .I Passtokey
98 d93fca6a 2005-02-11 devnull .I password
99 d93fca6a 2005-02-11 devnull into a DES key and stores the result in
100 d93fca6a 2005-02-11 devnull .IR key .
101 d93fca6a 2005-02-11 devnull It returns 0 if
102 d93fca6a 2005-02-11 devnull .I password
103 d93fca6a 2005-02-11 devnull could not be converted,
104 d93fca6a 2005-02-11 devnull and 1 otherwise.
