Fedora directory users - Jul 2007 - Sudo over tls/ssl connection

I am having a problem with sudo when I am running in a TSL/SSL connection, I
am able to ssh into the client and verified that the connection is secure,
but once logged in to the client machine I am unable to use sudo.

I am seeing multiple re-tries in the access logs that appear to close,:

When I do the same thing without a TLS/SSL connection sudo works fine.

Here is what I am seeing in the log

31/Jul/2007:15:48:18 -0500] conn=607 fd=74 slot=74 connection from
<ipaddr>
to <ipaddr>
[31/Jul/2007:15:48:18 -0500] conn=607 op=0 EXT
oid="1.3.6.1.4.1.1466.20037"
name="startTLS"
[31/Jul/2007:15:48:18 -0500] conn=607 op=0 RESULT err=0 tag=120 nentries=0
etime=0
[31/Jul/2007:15:48:18 -0500] conn=607 SSL 256-bit AES
[31/Jul/2007:15:48:18 -0500] conn=607 op=1 UNBIND
[31/Jul/2007:15:48:18 -0500] conn=607 op=1 fd=74 closed - U1

and eventually, I get

sudo: uid 1000 does not exist in the passwd file!

for the user config, it is simple, the user exists in ldap, the group exists
on the box (wheel) and I give the user in ldap a gid of 10

-bash-3.1$ id
uid=1000(testuser) gid=10(wheel) groups=10(wheel)

Thoughts?

Based on the symptoms and logs, this sounds more like a client problem
than a problem with FDS.  What OS / distro are you running?  What does
your /etc/ldap.conf look like?  Recent versions of Fedora, for
example, are fairly strict in how /etc/ldap.conf is configured.  The
following configuration works for me, although it could probably be
improved:

uri ldaps://ldap1.example.com/ ldaps://ldap2.example.com/
ssl on
tls_cacertfile /etc/pki/tls/certs/ca-localauthority.crt
host ldap1.example.com ldap2.example.com

This client is RHEL 5 -- I tried various different configs including the one
you paste below.

What I did find out eventually, is that sudo on rhel 5 is compiled with
libldap support, this was not the case in rhel 4.5 -- so I recompiled and
re-installed the rpm to exclude libldap support and it now it works fine.

Thanks,
