I do seem to remember something like that.
I thought I fixed that in RHEL-5.3.

But rev 0.rc2.102 is the RHEL-5.3 version?
Does it also happen with rev 0.rc2.102?

Hmm, apparently I had .88 and .102 installed at the same time. Let me reinstall autofs entirely and try again.

Nope, this still happens with autofs-5.0.1-0.rc2.102.el5_3.1

with automountInformation set to automountMapName=s2.persephone.bx.psu.edu,ou=automount,dc=bx,dc=psu,dc=edu

I'm seeing this:

This is using the [//servername/]dn syntax. The "old style" ldap:servername:mapname also does not work.

Maybe you need to explain a bit more.
Where is the map name in the above?

On second thought, looking closer at the log, post your LDAP
map, both the master map and the maps it referrers to.

I've been looking at these entries for a while now and I'm having
trouble understanding what your trying to achieve.

Can you describe how you believe this is supposed to work?
One thing is sure, whatever you're trying to do, it isn't setup
correctly.

Ian

Essentially, /nfs will contain a list of all nfs servers, then under each server we will have a list of all exports. What I'm trying to do is have each key under /nfs point to a mount map name for each server, so automountMapName=s2.persephone.bx.psu.edu will contain all of s2's mounts. 

This is kind of a more hard-coded way of doing a /net -hosts, but the difference being we have more control over mount options.

I have been using this same config through actual files for at least 3 years now, on everything from rhel2 on up with no problem whatsoever, where a key points to another mount map file. This way each server has all of its mounts in separate files. For example, /etc/auto.nfs would have a key for the s2 server that specified file:/etc/auto.nfs.s2.

Does that make sense?

Almost, except for the key being a map, that's not valid, but
the mount location can be a map though, when using submaps.

How about posting a couple of examples from your file map so
I can see what your doing their.

It sounds like your trying to use submaps, which is fine but
I suspect you may have been taking advantage of some file map
specific functionality that might not be specifically supported
so we might need to change to an expected syntax. Or the
translation from the file maps isn't quite right. In either
case, post the example and we will work out what we need to do.

Firstly, in comment #6, it appears you are happy to just give
the unqualified map names in the configuration and let autofs
fill in the extra bits. So lets continue that.

In /etc/nssswitch.conf you would have:

automount: ldap

Be aware that if /etc/nssswitch.conf has:

automount: files ldap

any map (or file) of the same name existing in /etc will
override the remote ldap map, however, in file maps you can
"+" include the remote ldap map as a means of providing host
specific local customization.

So, given this, a straight conversion of the map in comment #10,
with map name auto.nfs changed to auto_nfs and the rsize and wsize
changed to 32k should look something like:

#

In comment #10 you also gave the "--ghost" option to the submap,
and although I think the option should propagate from the master
map (you'll need to check that), the automountInformation
attribute above should read:

automountInformation: -fstype=autofs --ghost auto_nfs.s2

Ian

The --ghost does propogate.

The automountMapName attr shouldn't be on the automountKey=s2.persephone.bx.psu.edu entry.

This does work now. All of the examples I could find online used the syntax that I had posted before for specifying sub-mounts, and I guess it never ocurred to me that automountInformation could contain the same statements one would use in the files equivalent.

Is there a way to specify the sub mount map name (auto_nfs.s2  for example) by DN, instead of letting autofs search for this? I think you may have hinted that there was a way to do this.

Thanks for the help btw, and if this is all documented somewhere in the autofs package, I apologize for taking up your time. I thought I was following everything correctly as stated in auto.master(5), but I guess I missed something?

As long as you tell autofs that it is a submount, with the -fstype
option, you should be able to use any of the various "ldap:..."
syntax available. I think the problem previously was that this was
missing from the automountInformation and autofs was trying to
mount the dn.

Something like:

automountInformation: -fstype=autofs ldap:automountMapName=auto_nfs.s2,<rest of dn>

should work OK.

Perhaps it isn't clear, but ther should also be some examples
in /usr/share/doc/autofs-...., but I don't think they show
submount examples.

Ian

It looks like this issue is resolved.
Can you confirm that or comment on any ongoing problem please?

Issue is resolved, I've encountered no further problems.
