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 s Ar dir-list
38.Op Fl c Ar file-substring
39.Op Fl r Ar preferred-realm
40.Sh DESCRIPTION
41The
42.Nm
43program provides support for the kernel GSS-API implementation.
44.Pp
45The options are as follows:
46.Bl -tag -width indent
47.It Fl d
48Run in debug mode.
49In this mode,
50.Nm
51will not fork when it starts.
52.It Fl s Ar dir-list
53Look for an appropriate credential cache file in this list of directories.
54The list should be full pathnames from root, separated by ':' characters.
55Usually this list will simply be "/tmp".
56Without this option, the
57.Nm
58daemon assumes that the credential cache file is called /tmp/krb5cc_<uid>,
59where <uid> is the effective uid for the RPC caller.
60.It Fl c Ar file-substring
61Set a file-substring for the credential cache file names.
62Only files with this substring embedded in their names will be
63selected as candidates when the
64.Fl s
65has been specified.
66If not specified, it defaults to "krb5cc_".
67.It Fl r Ar preferred-realm
68Set a preferred Kerberos realm for the search of the directory list for
69a credentials cache file.
70When set, files with TGT credentials for this realm will be selected over
71other credential files.
72This option is only meaningful when the
73.Fl s
74option has been specified.
75.El
76.Sh FILES
77.Bl -tag -width ".Pa /etc/krb5.keytab" -compact
78.It Pa /etc/krb5.keytab
79Contains Kerberos service principals which may be used as credentials
80by kernel GSS-API services.
