Thanks indeed for the reply!
I updated the autofs package with version 5.0.5-30.el6.i686 and that error is gone now. But still automounting is not happening. Following is the relevant portion of /var/log/messages in one of the IPA client machine(RHEL 6.1 beta) configured with --mkhomedir switch .

Please note the following points,
-- All the configuration you had suggested for autofs & nsswitch had already been done -- My NFS server is another IPA client machine with RHEL 6.1(hugayat.cohort.org) -- This NFS server has /xtra/home/ as the NFS partition and /etc/exports file as follows
/xtra/home *(rw,fsid=0,insecure,no_subtree_check)/xtra/home gss/krb5(rw,fsid=0,insecure,no_subtree_check)/xtra/home gss/krb5i(rw,fsid=0,insecure,no_subtree_check)/xtra/home gss/krb5p(rw,fsid=0,insecure,no_subtree_check)
-- Output of the command ipa automountlocation-tofiles default

I have played various entries corresponding to /etc/auto.home (like /home instead of * ) but with no success.
Any idea ?

I think you ran into https://bugzilla.redhat.com/show_bug.cgi?id=579963
The ERR_remove_state call was removed in autofs-5.0.5-30.el6. I did a
quick test with that version and seemed to work fine.
As per the configuration, the necessary steps are:
1) edit /etc/nsswitch.conf and put "automount: ldap". It is also OK to
configure more sources such as "automount: files ldap".
2) edit /etc/sysconfig/autofs
You'll want to specify at least LDAP_URI and SEARCH_BASE according to
your server environment. In order for the correct attributes to be
searched for, you also need to uncomment the last set of attribute mappings:
MAP_OBJECT_CLASS="automountMap"
ENTRY_OBJECT_CLASS="automount"
MAP_ATTRIBUTE="automountMapName"
ENTRY_ATTRIBUTE="automountKey"
VALUE_ATTRIBUTE="automountInformation"
3) service autofs restart
If things still don't work, the logs should tell us more. If you run
autofs with -v -d it would even list the exact mount invocation, which
could be useful to determine the exact problem.
