Auth problems (LDAP backend with TLS)

I have a little problem with auth against LDAP. The host system is a SuSE Linux 10.1 x86_64.

Everything works fine on the system, IMAP, POP, login, SMB etc. etc.. But when trying to auth via a VMware service, either mui or client, I get this in my syslog:

vmware-authd\[7010]: pam_ldap: ldap_starttls_s: Connect error

My /etc/pam.d/vmware-authd contains:

auth     include        common-auth

account  include        common-account

password include        common-password

session  include        common-session

Ideas please?
