34.6. Configuring Maps

Configuring maps not only creates the maps, it associates mount points through the keys and it assigns mount options that should be used when the directory is accessed. IdM supports both direct and indirect maps.
Note
Different clients can use different map sets. Map sets use a tree structure, so maps cannot be shared between locations.
Important
Identity Management does not set up or configure autofs. That must be done separately. Identity Management works with an existing autofs deployment.

34.6.1. Configuring Direct Maps

Direct maps define exact locations, meaning absolute paths, to the file mount point. In the location entry, a direct map is identified by the preceding forward slash:
---------------------------
/etc/auto.direct:
/shared/man server.example.com:/shared/man

34.6.1.1. Configuring Direct Maps from the Web UI

  1. Click the Policy tab.
  2. Click the Automount subtab.
  3. Click name of the automount location to which to add the map.
  4. In the Automount Maps tab, click the + Add link to create a new map.
  5. In pop-up window, select the Direct radio button and enter the name of the new map.
  6. In the Automount Keys tab, click the + Add link to create a new key for the map.
  7. Enter the mount point. The key defines the actual mount point in the key name. The Info field sets the network location of the directory, as well as any mount options to use.
  8. Click the Add button to save the new key.

34.6.1.2. Configuring Direct Maps from the Command Line

The key defines the actual mount point (in the key name) and any options. A map is a direct or indirect map based on the format of its key.
Each location is created with an auto.direct item. The simplest configuration is to define a direct mapping by adding an automount key to the existing direct map entry. It is also possible to create different direct map entries.
Add the key for the direct map to the location's auto.direct file. The --key option identifies the mount point, and --info gives the network location of the directory, as well as any mount options to use. For example:
$ ipa automountkey-add raleigh auto.direct --key=/share --info="ro,soft,ipaserver.example.com:/home/share"
  Key: /share
  Mount information: ro,soft,ipaserver.example.com:/home/share
Mount options are described in the mount manpage, http://linux.die.net/man/8/mount.
On Solaris, add the direct map and key using the ldapclient command to add the LDAP entry directly:
ldapclient -a serviceSearchDescriptor=auto_direct:automountMapName=auto.direct,cn=location,cn=automount,dc=example,dc=com?one

34.6.2. Configuring Indirect Maps

An indirect map essentially specifies a relative path for maps. A parent entry sets the base directory for all of the indirect maps. The indirect map key sets a sub directory; whenever the indirect map location is loaded, the key is appended to that base directory. For example, if the base directory is /docs and the key is man, then the map is /docs/man.

34.6.2.1. Configuring Indirect Maps from the Web UI

  1. Click the Policy tab.
  2. Click the Automount subtab.
  3. Click name of the automount location to which to add the map.
  4. In the Automount Maps tab, click the + Add link to create a new map.
  5. In pop-up window, select the Indirect radio button and enter the required information for the indirect map:
    • The name of the new map
    • The mount point. The Mount field sets the base directory to use for all the indirect map keys.
    • Optionally, a parent map. The default parent is auto.master, but if another map exists which should be used, that can be specified in the Parent Map field.
  6. Click the Add button to save the new key.

34.6.2.2. Configuring Indirect Maps from the Command Line

The primary difference between a direct map and an indirect map is that there is no forward slash in front of an indirect key.
---------------------------
/etc/auto.share:
man     ipa.example.com:/docs/man
---------------------------
  1. Create an indirect map to set the base entry using the automountmap-add-indirect command. The --mount option sets the base directory to use for all the indirect map keys. The default parent entry is auto.master, but if another map exists which should be used, that can be specified using the --parentmap option.
    $ ipa automountmap-add-indirect location mapName --mount=directory [--parentmap=mapName]
    For example:
    $ ipa automountmap-add-indirect raleigh auto.share --mount=/share
    --------------------------------
    Added automount map "auto.share"
    --------------------------------
  2. Add the indirect key for the mount location:
    $ ipa automountkey-add raleigh auto.share --key=docs --info="ipa.example.com:/export/docs"
    -------------------------
    Added automount key "docs"
    -------------------------
      Key: docs
      Mount information: ipa.example.com:/export/docs
  3. To verify the configuration, check the location file list using automountlocation-tofiles:
    $ ipa automountlocation-tofiles raleigh
    /etc/auto.master:
    /-      /etc/auto.direct
    /share  /etc/auto.share
    ---------------------------
    /etc/auto.direct:
    ---------------------------
    /etc/auto.share:
    man     ipa.example.com:/export/docs
On Solaris, add the indirect map using the ldapclient command to add the LDAP entry directly:
ldapclient -a serviceSearchDescriptor=auto_share:automountMapName=auto.share,cn=location,cn=automount,dc=example,dc=com?one

34.6.3. Importing Automount Maps

If there are existing automount maps, these can be imported into the IdM automount configuration.
ipa automountlocation-import location map_file [--continuous]
The only required information is the IdM automount location and the full path and name of the map file. The --continuous option tells the automountlocation-import command to continue through the map file, even if the command encounters errors.
For example:
$ ipa automountlocation-import raleigh /etc/custom.map
