RE: autofs and OpenLDAP integration

["Mayers, Philip J" <p.mayers@ic.ac.uk>]

The problem is you're specifying *way* wrong stuff in your LDIF:

# This entry causes autofs to start up another automounter on /mci/mci.
dn: cn=mci,ou=auto.mci,dc=int-evry,dc=fr
objectClass: top
objectClass: automount
description: mci home directories
cn: mci
automountInformation: -fstype=autofs
openldap:ou=auto.mci.mci,dc=int-evry,dc=fr

WTF? That last line should be:

automountInformation: -fstype=autofs
ldap:openldap.int-evry.fr:ou=auto.mci.mci,dc=int-evry,dc=fr

However, see my other email - you just need to make the homdirectory be
"/mci/proccaci" or else approriately rename the LDAP OU's - I personally
wouldn't mess about with this recursive autofs stuff, although I didn't know
you could do it - cheers for the tip Nalin!

Whoa, that's freaky.  It should be using /usr/lib/autofs/lookup_ldap.so
for looking up entries using LDAP.

That's very strange.  Autofs is somehow determining that the map type is
"openldap" instead of "ldap", which is wrong.  It then uses the map type
to construct the path for the lookup module to use ("yp" maps are looked
up using lookup_yp.so, "nisplus" maps using lookup_nisplus.so, and so on).

Off-hand, a workaround would be to symlink lookup_openldap.so to
lookup_ldap.so in /usr/lib/autofs, but I'm stumped as to where it's
getting the wrong map type passed in, since the script is reporting the
right configuration setup.
