The grid-mapfile-add-entry program adds a new mapping from an X.509 distinguished name to a local POSIX user name to a gridmap file. Gridmap files are used as a simple authorization method for services such as GRAM5 or GridFTP.

The grid-mapfile-add-entry program verifies that the LOCAL-NAME is a valid user name on the system on which it was run, and that the mapping between DISTINGUISHED-NAME and LOCAL-NAME does not already exist in the gridmap file.

By default, grid-mapfile-add-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.

If the gridmap file does not exist, grid-mapfile-add-entry will create it. If it already exists, grid-mapfile-add-entry will save the current contents of the file to a new file with the string .old appended to the file name.

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

-help, -usage

Display the command-line options to grid-mapfile-add-entry.

-version, -versions

Display the version number of the grid-mapfile-add-entry command. The second form includes more details.


The X.509 distinguished name to add a mapping for. The name should be in OpenSSL\'s oneline format.


The POSIX user name to map the distinguished name to. This name must be a valid username. Add multiple LOCAL-NAME strings after the -ln command-line option. If any of the local names are invalid, no changes will be made to the gridmap file. Note that if multiple occurances of the -ln command-line option are present, only the the last one will be added.

-d, -dryrun

Verify local names and display diagnostics about what would be added to 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.


Add a mapping between the current user\'s certificate to the current user id to a gridmap file in $HOME/.gridmap:

% grid-mapfile-add-entry -f $HOME/.gridmap -dn "`grid-cert-info -subject`" -ln "`id -un`"

/home/juser/.gridmap does not exist... Attempting to create /home/juser/.gridmap
New entry:
"/DC=org/DC=example/DC=grid/CN=Joe User" juser
(1) entry added

Add a mapping between the a distinguished name and multiple local names:

% grid-mapfile-add-entry -dn "/DC=org/DC=example/DC=grid/CN=Joe User" juser" local1 local2

(1) entry added
