NAME¶

lcmaps_localaccount.mod - LCMAPS plugin to switch user identity

SYNOPSIS¶

lcmaps_localaccount.mod [-gridmapfile grid-mapfile]

DESCRIPTION¶

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.

OPTIONS¶

-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 /etc/grid-security/.

RETURN VALUES¶

LCMAPS_MOD_SUCCESS

Success.

LCMAPS_MOD_FAIL

Failure.

ENVIRONMENT¶

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 variables.

NOTES¶

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 is specified, the first is used. This requires LCMAPS version 1.6.0 or newer.
