29.Dt GSSD 8
30.Os
31.Sh NAME
32.Nm gssd
33.Nd "Generic Security Services Daemon"
34.Sh SYNOPSIS
35.Nm
36.Op Fl d
37.Op Fl o
38.Op Fl v
39.Op Fl s Ar dir-list
40.Op Fl c Ar file-substring
41.Op Fl r Ar preferred-realm
42.Sh DESCRIPTION
43The
44.Nm
45program provides support for the kernel GSS-API implementation.
46.Pp
47The options are as follows:
48.Bl -tag -width indent
49.It Fl d
50Run in debug mode.
51In this mode,
52.Nm
53will not fork when it starts.
54.It Fl o
55Force use of DES and the associated old style GSS-API initialization token.
56This may be required to make kerberized NFS mounts work against some
57non-FreeBSD NFS servers.
58.It Fl v
59Run in verbose mode.
60In this mode,
61.Nm
62will log activity messages to syslog using LOG_INFO | LOG_DAEMON or to
63stderr, if the
64.Fl d
65option has also been specified.
66The minor status is logged as a decimal number, since it is actually a
67Kerberos return status, which is signed.
68.It Fl s Ar dir-list
69Look for an appropriate credential cache file in this list of directories.
70The list should be full pathnames from root, separated by ':' characters.
71Usually this list will simply be "/tmp".
72Without this option,
73.Nm
74assumes that the credential cache file is called /tmp/krb5cc_<uid>,
75where <uid> is the effective uid for the RPC caller.
76.It Fl c Ar file-substring
77Set a file-substring for the credential cache file names.
78Only files with this substring embedded in their names will be
79selected as candidates when
80.Fl s
81has been specified.
82If not specified, it defaults to "krb5cc_".
83.It Fl r Ar preferred-realm
84Use Kerberos credentials for this realm when searching for
85credentials in directories specified with
86.Fl s .
87If not specified, the default Kerberos realm will be used.
88.El
89.Sh FILES
90.Bl -tag -width ".Pa /etc/krb5.keytab" -compact
91.It Pa /etc/krb5.keytab
92Contains Kerberos service principals which may be used as credentials
93by kernel GSS-API services.
94.El
95.Sh EXIT STATUS
96.Ex -std

98.Xr gssapi 3 ,
