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. The format 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: 1.2.3.45464.3.1

       The 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. If no comment is
       specified, the gsscred utility inserts a comment that specifies the user name as an ASCII string and  the  GSS-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. At least one of the follow-
       ing options must be specified: -n, -u, or -m. If no security mechanism is specified, then all entries will be deleted for the user  identi-
       fied 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 the gsscred 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.

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 Security Mechanism

       The 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

       Example 3: Listing All User Mappings for the Kerberos v5 Security Mechanism

       The following lists all user mappings for the kerberos v5 security mechanism.

       example% gsscred -m kerberos_v5 -l

       Example 4: Listing All Mappings for All Security Mechanism for a Specified User

       The following lists all mappings for all security mechanisms for the user bsimpson.

       example% gsscred -n bsimpson -l

EXIT STATUS

       The following exit values are returned:

       0               Successful completion.

       >0              An error occurred.

NOTES

       Some  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.
