Thanks for the confirmation that this is indeed not very well supported 
:).  I went down this route because I find it tedious to have to import 
CA certs into browsers and particularly into Thunderbird for accessing 
ldap address book directories.  If there are suggestions for other ways 
to handle this, I would be appreciative.  Otherwise I'll keep plugging 
away at this.

Do let me know if this is just not going to be supported though.
