System Administration Commands gsscred(1M)
NAME
gsscred - add, remove, and list gsscred table entries
SYNOPSIS
gsscred [-n user [-o oid] [-u uid]] [-c comment] -m mech -a
gsscred [-n user [-o oid]] [-u uid] [-m mech] -r
gsscred [-n user [-o oid]] [-u uid] [-m mech] -l
DESCRIPTION
The gsscred utility is used to create and maintain a mapping
between a security principal name and a local UNIX uid. Theformat of the user name is assumed to be GSS_C_NT_USER_NAME.
You can use the -o option to specify the object identifier
of the name type. The OID must be specified in dot-separated
notation, for example: 1.2.3.45464.3.1The gsscred table is used on server machines to lookup the
uid of incoming clients connected using RPCSEC_GSS.
When adding users, if no user name is specified, an entry is created in the table for each user from the passwd table. Ifno comment is specified, the gsscred utility inserts a com-
ment that specifies the user name as an ASCII string and theGSS-APIsecurity mechanism that applies to it. The security
mechanism will be in string representation as defined in the /etc/gss/mech file.The parameters are interpreted the same way by the gsscred
utility to delete users as they are to create users. Atleast one of the following options must be specified: -n,
-u, or -m. If no security mechanism is specified, then all
entries will be deleted for the user identified by either the uid or user name. If only the security mechanism is specified, then all user entries for that security mechanism will be deleted. Again, the parameters are interpreted the same way by thegsscred utility to search for users as they are to create
users. If no options are specified, then the entire table is returned. If the user name or uid is specified, then all entries for that user are returned. If a security mechanism is specified, then all user entries for that security mechanism are returned.SunOS 5.11 Last change: 11 Feb 2004 1
System Administration Commands gsscred(1M)
OPTIONS-a Add a table entry.
-c comment Insert comment about this table entry.
-l Search table for entry.
-m mech Specify the mechanism for which this name is
to be translated.-n user Specify the optional principal name.
-o oid Specify the OID indicating the name type of
the user.-r Remove the entry from the table.
-u uid Specify the uid for the user if the user is
not local.EXAMPLES
Example 1 Creating a gsscred Table for the Kerberos v5 Secu-
rity MechanismThe following shows how to create a gsscred table for the
kerberos v5 security mechanism. gsscred obtains user names
and uid's from the passwd table to populate the table.example% gsscred -m kerberos_v5 -a
Example 2 Adding an Entry for root/host1 for the Kerberos v5 Security Mechanism The following shows how to add an entry for root/host1 with a specified uid of 0 for the kerberos v5 security mechanism.example% gsscred -m kerberos_v5 -n root/host1 -u 0 -a

NOTESSome GSS mechanisms, such as kerberos_v5, provide their own
authenticated-name-to-local-name (uid) mapping and thus do
not usually have to be mapped using gsscred. See
gsscred.conf(4) for more information.
