I'm using PADL's nss_ldap 220 and pam_ldap 169, openldap 2.2.13 patched for
issue #2982, cyrus sasl 2.1.19, and mit kerberos 1.3.4 on RedHat 9.  My
directory server is a Windows 2003 domain controller with SFU 3.5 installed.  I
have everything built, configured, and working using sasl GSSAPI for
authentication.  

The problem is that I am getting random occurrences of "io.c:710: ber_get_next:
Assertion '0' failed."  It's some sort of timing problem.  When I turn on
debugging the problem goes away.  When I turn debugging off, sometimes the
problem comes back.  Since the linux machine is actually a vmware image, I moved
it to a faster box and the problem got much worse.  It was so bad I was able to
reproduce it with the debugging level at 65535.  The ps command seems to have a
higher rate of failure.  I'm seeing 'Unable to chase referral
"ldap://ForestDnsZones.msildap.cybersafe.com/DC=ForestDnsZones,DC=msildap,DC=cybersafe,DC=com";
(Can't contact LDAP server)' before the assertion and after a varying number of
requests.  Unfortunately I cannot reproduce this with ldapsearch since
ldapsearch chases referrals anonymously which isn't allowed by my domain
controller.

Below is a small portion of the debugging output from immediately before the
assertion.  I can give you as much as you want but I have over 46,000 lines of
it.
