Remove entries from a gridmap file

Synopsis

grid-mapfile-delete-entry [ -help | -usage | -version | -versions ]

grid-mapfile-delete-entry -dn DISTINGUISHED-NAME -ln LOCAL-NAME... [ -d | -dryrun ] [ -mapfile MAPFILE | -f MAPFILE ]

The grid-mapfile-delete-entry program deletes mappings from a gridmap file. If both the -dn and -ln options are specified, grid-mapfile-delete-entry removes entries which meet both criteria (remove entries mapping DISTINGUISHED-NAME to LOCAL-NAME for each LOCAL-NAME specified). If only -dn or -ln is specified all entries for the specified DISTINGUISHED-NAME or LOCAL-NAME are removed.

By default, grid-mapfile-delete-entry will modify the gridmap file named by the GRIDMAP environment variable if present, or the file /etc/grid-security/grid-mapfile if not. This can be changed by the use of the -mapfile or '-f command-line options.

Prior to modifying a gridmap file, grid-mapfile-delete-entry saves its current contents to a file with the string .old appended to the original file name.

The full set of command-line options to grid-mapfile-delete-entry are:

-help, -usage: Display the command-line options to grid-mapfile-delete-entry.
-version, -versions: Display the version number of the grid-mapfile-delete-entry command. The second form includes more details.
-dn DISTINGUISHED-NAME: The X.509 distinguished name to remove from the gridmap file. If the -ln option is not specified, remove all entries for this name; otherwise, remove entries that match both this name and the local name. The name should be in OpenSSL’s oneline format.
-ln LOCAL-NAME...: The POSIX user name to remove from the gridmap file. Include multiple LOCAL-NAME strings after the -ln command-line option to remove multiple names from the gridmap. If the -dn option is not specifeid, remove all entries for these names; otherwise, remove entries that match the DISTINGUISHED-NAME and any of the LOCAL-NAME values.
-d, -dryrun: Display diagnostics about what would be removed from the gridmap file, but don’t actually modify the file.
-mapfile MAPFILE, -f MAPFILE: Modify the gridmap file named by MAPFILE instead of the default.

Examples

Remove all mappings for a distinguished name:

% grid-mapfile-delete-entry "/DC=org/DC=example/DC=grid/CN=Joe User"
Modifying /etc/grid-security/grid-mapfile ...
Deleting entry: "/DC=org/DC=example/DC=grid/CN=Joe User" juser,juser2
(1) entry deleted

Remove the mapping between a distinguished name and a single local username:

% grid-mapfile-delete-entry "/DC=org/DC=example/DC=grid/CN=Joe User" -ln juser2
Modifying /etc/grid-security/grid-mapfile ...
Current entry: "/DC=org/DC=example/DC=grid/CN=Joe User" juser
(1) mapping removed: (juser2), (0) not present and ignored
(0) entries deleted
