Re: AutoFS problem with OpenLDAP server

[Erich Weiler <weiler@soe.ucsc.edu>]

OK, I figured out that AutoFS looks at "/etc/openldap/ldap.conf" and NOT 
"/etc/ldap.conf".  I'm one step closer.  However, when I copy my 
ldap.conf over to /etc/openldap/ldap.conf, and do a "/etc/init.d/autofs 
start", it still gives me the:

Starting automount: No Mountpoints Defined

Error at the command line.  I *DO* see traffic to the Openldap server 
this time though, and in the OpenLDAP logs I see:

ber_scanf fmt ({mm}) ber:
ber_scanf fmt ({mm}) ber:
     filter: (&(?=undefined)(?=undefined))
ber_scanf fmt ({M}}) ber:
     attrs: automountMapName automountInformation
==> limits_get: conn=10642 op=6 dn="[anonymous]"
=> bdb_search
bdb_dn2entry("dc=domain,dc=com")

So it looks like the automounter is searching for "automountMapName" and 
"automountInformation".  Which is bad, because my maps are in the form 
of "nisMapName" and "nisMapEntry".  Does anyone know if there is an easy 
way to tell the automounter to look for the other attributes?  Or do I 
have to try to set up some kind of aliasing on my OpenLDAP server?

Thanks for your patience with me!

ciao, erich
