lcmaps_localaccount.mod - LCMAPS plugin to switch user identity
This plugin is an acquisition plugin and will provide the LCMAPS system with
Local Account credential information. The plugin tries to find a local account
(more specifically a UserID) based on the Distinguished Name (DN) of the
user's end-entity certificate.
It will try to find a DN to local account name mapping in the grid-mapfile. The
plugin will resolve the UID, GID and all the secondary GIDs of the mapped
local (system) account username.
- -gridmapfile grid-mapfile
- This file must contain DNs to (local) user account name
mappings. It is strongly advised to set this option and to set it to an
absolute path to avoid usage of the wrong file(path). When unset, the
plugin will try to obtain the value from one of the environment variables
(see ENVIRONMENT). When those are also unset, the default depends
on whether the plugin runs inside a (setuid-)root application. In the
(setuid-)root case, the default is /etc/grid-security/grid-mapfile.
In the non-(setuid-)root case, the default is
<homedir>/.gridmap. If that latter default does not exist,
the plugin will return the account information of the calling user. In a
(setuid-)root application, relative paths are taken with respect to
- GRIDMAP | GLOBUSMAP | globusmap | GlobusMap
- When no grid-mapfile is specified as option to the plugin,
it will try to obtain the file location from one of these environment
Since version 1.6.0 the localaccount plugin supports grid-mapfile entries with
multiple usernames, separated by a comma without whitespace. This can be used
in combination with specifying a requested username
(such as by
gsissh), to pick any of these accounts. When no requested username
specified, the first is used. This requires LCMAPS version 1.6.0 or newer.
