problem with autofs

[-- Attachment #1.1: Type: text/plain, Size: 745 bytes --]

Hello Evrybuddy,

I had configured Openldap and succesfully configured for authentication of
users.I'm facing problem with autofs.

I'm using Rhel4.When i say service autofs start it says

No mount points defined.

I have written the correct entries in /etc/exports file.

I have sucessfully mounted directories using /etc/auto.master and indirect
maps on the client side
But when i'm using the ldap maps it's giving me problems
How can i make my autofs service to read the auto.master from LDAP Ou=
auto.master.

I have changed in the /etc/nsswitch.conf file to Automount: ldap but no use

when i use service autofs start it says "No mountpoints defined".

Are they any bugs with RHEL4?
Or am i going wrong somewhere?

Thanks in advance
Abdul.

You need to show us your maps.

Bugs?  In software?  Nooo, none here.  ;)

Since you can authenticate users using ldap, I'm guessing that your
/etc/openldap/ldap.conf file points to the right server with the right base
DN.  If that is the case, then we'll need to see the ldif for your master
map, as Ian noted in his reply.

What version of autofs are you using?  What LDAP schema are you using?

The ldif for master is like this.

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

dn: cn=/home,ou=auto.master,dc=testlab,dc=com
objectClass:automount
cn:/home
automountInformation: ldap server.testlab.com:ou=auto.home,dc=testlab,dc=com
--timeout 60


Auto.Home

 dn: ou=auto.home,dc=testlab,dc=com
objectClass:top
objectClass:automountMap
ou:auto.home

dn: cn=user1,ou=auto.home,dc=testlab,dc=com
objectClass: automount
cn:user1
automountInformation: -fstype=nfs,hard,intr server.testlab.com:/home/user1

I'm using 4.1.3-155 version of autofs

My problem is to tell autofs daemon to read the map from LDAP and not from
files.
My autofs reads from the file /etc/auto.master.
If i give the entry

/home ldap:server.testlab.com:ou=auto.home,dc=testlab,dc=com

in the /etc/auto.master file and say Service autofs status

Then i see the mount point as the above.But when i try to login on the
client side.Still it doesn't mount the user's home directory.

I have changed the entry AUTOMOUNT:LDAP in /etc/nsswitch.conf file.

Thanks,
Abdul

Well, for that problem we may need debug logs, but let's sort out your
issue with reading the master map from LDAP, first.

syedk> I have changed the entry AUTOMOUNT:LDAP in /etc/nsswitch.conf file.

Every time you type this in, you change the case.  Make sure that
nsswitch.conf reads:

automount: ldap

It should all be lower-case, as otherwise the init script will not match
it.  If it is lower-case, then please send along the output from:
  "sh -x /etc/init.d/autofs start"

It may also be useful to see the output from:
   /usr/lib[64]/autofs/autofs-ldap-auto-master

Thanks,

Jeff

You refer to "the client side", you do mean the client that is running
autofs with the configuration you describe above, don't you?

Hi Kent,

I mean when i write the map in the /etc/auto.master also it doesn't make any
difference when i login with the username on the client machine which is
configured to use LDAP and autofs.

Thanks,
Abdul

That's bad.  What does the following show?

  ldapsearch -x -s subtree '(&(objectclass=automountMap)(ou=auto.master))'

Is the ldap server configured to allow anonymous binds?

Hi Jeff,
Here's the output

objectClass:top
objectClass:automountMap
ou:auto.master

I have configured to allow anonymous bind.No ACLS are given

OK, then what do you get with this:

ldapsearch -x -s subtree -b 'ou=auto.master,dc=testlab,dc=com' 'objectclass=automount'

Jeff,
It gives me

dn: cn=/home,dc=testlab,dc=com
and the automount information which i specified in the auto.home map.

I think Ldap entries are fine,but the problem is to make autofs read from
the LDAP rather than files.

Thanks,
Abdul.

No. The problem right now is to understand why the
autofs-ldap-auto-master program is not able to read the LDAP master map.
