grid-mapfile-delete-entry
GRID-MAPFILE-DELET(8) Globus Commands GRID-MAPFILE-DELET(8)
NAME
grid-mapfile-delete-entry - 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]]
DESCRIPTION
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 that 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

GRIDMAP
