[clug] LDAP over SSL/TLS not working

On debian systems there are 3 ldap conf files: /etc/ldap/ldap.conf, / 
etc/libnss_ldap.conf and /etc/pam_ldap.conf.  They are all slightly  
different and have overlapping sets of configuration directives.  The  
names are indicative of what they are for.  I guess /etc/ldap/ 
ldap.conf is equivalent to RH /etc/openldap/ldap.conf
