Migration from NIS & Automount to LDAP & Automount under Redhat 7.2: something is broken?

[Jose Vicente Nunez Z <josevnz@newbreak.com>]

Greetings,

Hi to all,

I'm getting problems to migrate from NIS+Automount to LDAP+Automount;
Looks like the PADL tool doesn't generate the proper code, but code to
be used as a NIS map.

This is the Redhat schema for automount,
/etc/openldap/schema/redhat/autofs.schema:


# Depends upon core.schema and cosine.schema

# OID Base is 1.3.6.1.4.1.2312.4
#
# Attribute types are under 1.3.6.1.4.1.2312.4.1
# Object classes are under 1.3.6.1.4.1.2312.4.2
# Syntaxes are under 1.3.6.1.4.1.2312.4.3

# Attribute Type Definitions

attributetype ( 1.3.6.1.1.1.1.25 NAME 'automountInformation'
        DESC 'Information used by the autofs automounter'
        EQUALITY caseExactIA5Match
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE )

objectclass ( 1.3.6.1.1.1.1.13 NAME 'automount' SUP top STRUCTURAL
        DESC 'An entry in an automounter map'
        MUST ( cn $ automountInformation )
        MAY ( description ) )

objectclass ( 1.3.6.1.4.1.2312.4.2.2 NAME 'automountMap' SUP top
STRUCTURAL
        DESC 'An group of related automount objects'
        MUST ( ou ) )


But if a run the migration tools (the one that comes with the Os are
exactly the same as the ones at the PADL site): i got the following:

Auto.master:

[root@lnxdev0002 MigrationTools]# perl migrate_automount.pl
/etc/auto.master 
dn: nisMapName=auto.master,dc=ZZZ,dc=YYYY,dc=XXX
objectClass: top
objectClass: nisMap
nisMapName: auto.master

dn: cn=/home,nisMapName=auto.master,dc=ZZZ,dc=YYYY,dc=XXX
objectClass: nisObject
cn: /home
nisMapEntry: auto.home -rw,intr,rsize=4096,wsize=4096,acdirmin=40
nisMapName: auto.master

dn: cn=/nb_apps,nisMapName=auto.master,dc=ZZZ,dc=YYYY,dc=XXX
objectClass: nisObject
cn: /nb_apps
nisMapEntry:   auto.nb_apps -rw,intr,rsize=4096,wsize=4096,acdirmin=40
nisMapName: auto.master

dn: cn=/data,nisMapName=auto.master,dc=ZZZ,dc=YYYY,dc=XXX
objectClass: nisObject
cn: /data
nisMapEntry:   auto.data -rw,intr,rsize=4096,wsize=4096,acdirmin=40
nisMapName: auto.master

[root@lnxdev0002 MigrationTools]# 

Auto.home:

[root@lnxdev0002 MigrationTools]# perl migrate_automount.pl
/etc/auto.home   
dn: nisMapName=auto.home,dc=ZZZ,dc=YYYY,dc=XXX
objectClass: top
objectClass: nisMap
nisMapName: auto.home

dn: cn=user1,nisMapName=auto.home,dc=ZZZ,dc=YYY,dc=XXX
objectClass: nisObject
cn: user1
nisMapEntry: lnxdev0002:/export/home/&
nisMapName: auto.home

dn: cn=user2,nisMapName=auto.home,dc=ZZZ,dc=YYY,dc=XXX
objectClass: nisObject
cn: user2
nisMapEntry: lnxdev0002:/export/home/&
nisMapName: auto.home


But according to the OpenLdap site
(http://www.openldap.org/faq/data/cache/599.html) the Schema in autofs
is broken and should work with something like this:


The following example has been tested with autofs 4.0:

dn: ou=auto.master, dc=example, dc=com
objectClass: top
objectClass: automountMap
ou: auto.master

dn: cn=/home, ou=auto.master, dc=ZZZ,dc=YYY,dc=XXX
objectClass: automount
cn: /home
automountInformation: ldap
ldapserver.example.com:ou=auto.home,dc=ZZZ,dc=YYY,dc=XXX

dn: ou=auto.home, dc=ZZZ,dc=YYY,dc=XXX
objectClass: top
objectClass: automountMap
ou: auto.home

dn: cn=user1, ou=auto.home, dc=example, dc=com
objectClass: automount
cn: user1
automountInformation: -fstype=nfs,hard,intr,nodev,nosuid
nfsserver.example.com:/home/user1

dn: cn=user2, ou=auto.home, dc=example, dc=com
objectClass: automount
cn: user2
automountInformation: -fstype=nfs,hard,intr,nodev,nosuid
nfsserver.example.com:/home/user2

I got several questions:

1) I'm i wrong here? I would like to know also if i have to write a
script to do it myself or if there something out there i can use.

2) I read also than there is no easy way to tell autofs to get the
auto.master from LDAP directly (just like autofs used to be with NIS)
but you need to "hack it" running a script or adding a ldap syntax
directly (http://www.openldap.org/faq/data/cache/599.html,
http://www.ccm.ece.vt.edu/~lscharf/samd/index.php?topic=LDAP).

Thanks in advance,

JV.
