Martin Babinsky 1f0959735f differentiate between limit types when LDAP search exceeds configured limits 
When LDAP search fails on exceeded limits, we should raise an specific
exception for the type of limit raised (size, time, administrative) so that
the consumer can distinguish between e.g. searches returning too many entries
and those timing out.

Automount
Stores automount(8) configuration for autofs(8) in IPA.
The base of an automount configuration is the configuration file auto.master.
This is also the base location in IPA. Multiple auto.master configurations
can be stored in separate locations. A location is implementation-specific
with the default being a location named 'default'. For example, you can have
locations by geographic region, by floor, by type, etc.
Automount has three basic object types: locations, maps and keys.
A location defines a set of maps anchored in auto.master. This allows you
to store multiple automount configurations. A location in itself isn't
very interesting, it is just a point to start a new automount map.
A map is roughly equivalent to a discrete automount file and provides
storage for keys.
A key is a mount point associated with a map.
When a new location is created, two maps are automatically created for
it: auto.master and auto.direct. auto.master is the root map for all
automount maps for the location. auto.direct is the default map for
direct mounts and is mounted on /-.
An automount map may contain a submount key. This key defines a mount
location within the map that references another map. This can be done
either using automountmap-add-indirect --parentmap or manually
with automountkey-add and setting info to "-type=autofs :<mapname>".
EXAMPLES:
Locations:
Create a named location, "Baltimore":
ipa automountlocation-add baltimore
Display the new location:
ipa automountlocation-show baltimore
Find available locations:
ipa automountlocation-find
Remove a named automount location:
ipa automountlocation-del baltimore
Show what the automount maps would look like if they were in the filesystem:
ipa automountlocation-tofiles baltimore
Import an existing configuration into a location:
ipa automountlocation-import baltimore /etc/auto.master
The import will fail if any duplicate entries are found. For
continuous operation where errors are ignored, use the --continue
option.
Maps:
Create a new map, "auto.share":
ipa automountmap-add baltimore auto.share
Display the new map:
ipa automountmap-show baltimore auto.share
Find maps in the location baltimore:
ipa automountmap-find baltimore
Create an indirect map with auto.share as a submount:
ipa automountmap-add-indirect baltimore --parentmap=auto.share --mount=sub auto.man
This is equivalent to:
ipa automountmap-add-indirect baltimore --mount=/man auto.man
ipa automountkey-add baltimore auto.man --key=sub --info="-fstype=autofs ldap:auto.share"
Remove the auto.share map:
ipa automountmap-del baltimore auto.share
Keys:
Create a new key for the auto.share map in location baltimore. This ties
the map we previously created to auto.master:
ipa automountkey-add baltimore auto.master --key=/share --info=auto.share
Create a new key for our auto.share map, an NFS mount for man pages:
ipa automountkey-add baltimore auto.share --key=man --info="-ro,soft,rsize=8192,wsize=8192 ipa.example.com:/shared/man"
Find all keys for the auto.share map:
ipa automountkey-find baltimore auto.share
Find all direct automount keys:
ipa automountkey-find baltimore --key=/-
Remove the man key from the auto.share map:
ipa automountkey-del baltimore auto.share --key=man

Developer notes:
RFC 2707bis http://www.padl.com/~lukeh/rfc2307bis.txt
A few notes on automount:
- The default parent when adding an indirect map is auto.master
- This uses the short format for automount maps instead of the
URL format. Support for ldap as a map source in nsswitch.conf was added
in autofs version 4.1.3-197. Any version prior to that is not expected
to work.
- An indirect key should not begin with /
As an example, the following automount files:
auto.master:
/- auto.direct
/mnt auto.mnt
auto.mnt:
stuff -ro,soft,rsize=8192,wsize=8192 nfs.example.com:/vol/archive/stuff
are equivalent to the following LDAP entries:
# auto.master, automount, example.com
dn: automountmapname=auto.master,cn=automount,dc=example,dc=com
objectClass: automountMap
objectClass: top
automountMapName: auto.master
# auto.direct, automount, example.com
dn: automountmapname=auto.direct,cn=automount,dc=example,dc=com
objectClass: automountMap
objectClass: top
automountMapName: auto.direct
# /-, auto.master, automount, example.com
