[LDAP schema used by autofs]

The following shows an example of a direct AutoFS map, auto_direct, stored in the LDAP directory server using new (rfc-2307bis) automount schema:
{{{
dn:automountMapName=auto_direct,dc=nishpind
objectClass: top
objectClass: automountMap
automountMapName: auto_direct
 
 
dn:automountKey=/mnt_direct/test1,automountMapname=auto_direct, dc=nishpind
objectClass: top
objectClass: automount
automountInformation:hostA:/tmp 
automountKey: /mnt_direct/test1

dn:automountKey=/mnt_direct/test2,automountMapname=auto_direct, dc=nishpind
objectClass: top
objectClass: automount
automountInformation:hostB:/tmp
automountKey:/mnt_direct/test2
}}}

Automounts become a DIT structure similar to:
{{{
dc=com
|--dc=willeke
|---ou=Unix
|----automountMapName=auto_direct
|-----automountKey=/mnt_direct/test1
|-----automountKey=/mnt_direct/test2
}}}

!!The nisObject Automount (rfc-2307) Schema 

The nisObject automount schema defines nisMap and nisObject structures to represent the AutoFS maps and their entries. The AutoFS maps are stored in the LDAP directory server using the nisMap and nisObject structures.
An Example

The following shows an example of a direct AutoFS map, auto_direct, stored in the LDAP directory server using the nisObject automount schema:
{{{
dn:nisMapName=auto_direct,dc=nishpind
objectClass: top
objectClass: nisMap
nisMapName: auto_directdn:cn=/mnt_direct/test1, nisMapName=auto_direct, dc=nishpind
objectClass: top
objectClass: nisObject
nisMapName: auto_direct
cn: /mnt_direct/test1
nisMapEntry:hostA:/tmp 

dn:cn=/mnt_direct/test2, nisMapname=auto_direct, dc=nishpind
objectClass: top
objectClass: nisObject
nisMapName: auto_direct
cn: /mnt_direct/test2
nisMapEntry:hostB:/tmp
}}}

!!!Limitations
The nisObject automount schema contains three attributes:
* cn
* nisMapEntry
* nisMapName. 
cn is an attribute that ignores case-matching. Consider the following example:
{{{
# an indirect map named auto_test
test1    server1:/source
TEST1    server2:/source
}}}
In the above example, because the cn attribute is case-insensitive, the LDAP considers “cn=TEST1, nisMapName=auto_test” to be a redefinition of “cn=test1, nisMapName=auto_test”.

Using the nisObject automount map schema, capital letters are not significant. In other words, if two keys have names that are only different by the use of capital letters, then one of those entries will be rendered inoperable because the other one is the only one that can be retrieved.
	
NOTE: If you use the nisObject automount map schema, do not use any keys that have capital letters and only differ from other keys by those capital letters.
