CentOS - Oct 2008 - LDAP and expired passwords

CentOS 5.2 with OpenLDAP 2.3.27, nss_ldap_253.13, using TLS, i686 and 
x86_64.

If a user with an expired password (shadowLastChange + shadowMax < current 
day) logs in to a system where ldap.conf points first to a consumer-only 
LDAP server, the password change operation (exop) proceeds and fails with:

 	LDAP password information update failed: Referral

If I comment out "ssl start_tls", the referral to the master is
followed
and the password change operation succeeds. I've found references to 
problems with earlier releases of pam_ldap when referrals were not 
properly followed when using TLS, and these are supposed to be fixed; 
apparently not in my case. Can anyone hit me with the clue stick?

Does the common name in the certificate or the x509 v3 extensions match
the hostname used in the referral in your slapd.conf?  Is the
certificate issued by the ldap server you are being referred to signed
by a trusted CA?  Following referrals using start_tls works just fine
for me.
