Hi Ian,
reply from custom:
==>
Just to clarify:
1. We use different basedn for authentication and automount in our
directory. The basedn for authentoication is used from /etc/ldap.conf.
However we need to specify a separate basedn for automount maps because
they are regional.
2. We do not have multiple master maps just one.
If it possible to use the MASTER_MAP_NAME without specifying the server
then that should solve our problem. I will test this and let you know if
it works.
<==
thanks,
wengang.

Just to give you a little more information: Our automount schema is
based on
the "automountmapname", "automountkey" and "automountinformation"
attributes.
This works properly with the relevant settings in
the /etc/sysconfig/autofs
file on RHEL5 if the basedn is set manually in
the /etc/openldap/ldap.conf
But doesn't work if you don't set basdn in ldap.conf?
Are you saying that there are multiple master maps and maps of the same
name under different basedns in this setup?
file. However, since the openldap/ldap.conf file can be used by other
applications, we don't want our automounter's basedn to depend on
this.
The LDAP attributes of the automount maps are as shown below:
[EMAIL PROTECTED] ~]$ ldapsearch -LLL -x -b
"ou=sc,ou=ca,ou=na,dc=hyperion,dc=com"
"automountmapname=auto_nfshome"
dn:
automountMapName=auto_nfshome,ou=sc,ou=ca,ou=na,dc=hyperion,dc=com
objectClass: top
objectClass: automountMap
automountMapName: auto_nfshome
[EMAIL PROTECTED] ~]$ ldapsearch -LLL -x -b
"automountmapname=auto_nfshome,ou=sc,ou=ca,ou=na,dc=hyperion,dc=com"
"automountkey=plakdawa"
dn:
automountkey=plakdawa,automountMapName=auto_nfshome,ou=sc,ou=ca,ou=na,dc=h
yperion,dc=com
automountInformation: scfs3:/vol/vol2/homes/&
automountKey: plakdawa
objectClass: top
objectClass: automount

The other issue with the DEFAULT_MASTER_MAP_NAME is that providing the full
URL, will prevent the failover to the secondary LDAP server should the one
mentioned in the URL fail. Or is it possible to add secondary entries?
It's possible to specify the map (master or other) without the server
name.
eg.
MASTER_MAP_NAME="ou=auto.master,dc=themaw,dc=net"
This will then use the above basedn for finding the master map.
However, this can't be used when autofs searches for the basedn for the
maps referred to in the above master map which may not be a sensible
thing to do but cannot be practically done another way.
The only workaround for this at the moment would be to specify the
basedn in the master map entries as well as in the master map as above.
eg.
# /ldap, auto.master, themaw.net
dn: cn=/ldap,ou=auto.master,dc=themaw,dc=net
objectClass: automount
cn: /ldap
automountInformation: ou=auto.indirect,dc=themaw,dc=net
