Stumped - SSL works for auth, sudo, etc, but fails for ldap user cronjobs

[David Nguyen]

Hi all,

I have a strange one.  My current setup is working perfectly.  client1
is able to connect to ldap-server1 via SSL and everything is working
correctly. I then had a need to add another ldap server (ldap-server2)
as a multi-master replica and everything is working (user auth, sudo
via ldap users, ldapsearch, openssl, etc) except cronjobs for users
served out of ldap fail to run.

I can see this in the error log on ldap-server2:

[18/Jul/2012:11:18:00 -0700] - PR_Recv for connection 467 returns
-12195 (Peer does not recognize and trust the CA that issued your
certificate.)

If I set /etc/ldap.conf to not use SSL (URI ldap://fqdn vs URI
ldaps://fqdn:636), the cronjobs fire just fine.

So it appears as though there is an SSL cert issue, but I'm stumped
because all of the other services that use ldap on client1 work except
cron jobs (root cron fires fine as expected since nsswitch is set to
files then ldap).

If I replace the URI string in /etc/ldap.conf to point at
ldap-server1, cron starts working.

Both ldap-server1 and ldap-server2 are using running the same OS and
kernel version (RHEL5) as well as the same version of 389 DS
(389-ds-1.2.1-1.el5).

Any ideas as to what could be causing this problem?   Here is the
/etc/ldap.conf on client1 if it matters:

====== begin /etc/ldap.conf =======
URI ldaps://ops-ldap006.svale.netledger.com:636
base dc=netsuite,dc=com

Thanks in advance,
