SUNWtlsu which installs in /usr/sfw/bin/certutil. It's in my install. I
don't recall if I did any CD swapping during the install or not, though
I installed x86 from iso.

I'd check the 389-ds access log for connection problems.

This works for me:

ldapclient -v manual -a authenticationMethod=tls:simple \
 -a defaultSearchBase=dc=example,dc=com \
 -a defaultServerList=ipa.example.com \
 -a serviceSearchDescriptor=passwd:cn=users,cn=accounts,dc=example,dc=com \
 -a serviceSearchDescriptor=group:cn=groups,cn=compat,dc=example,dc=com \
 -a proxyDN=uid=solaris,cn=sysaccounts,cn=etc,dc=example,dc=com \
 -a proxyPassword=secret123 \
 -a objectclassMap=shadow:shadowAccount=posixAccount

I'd suggest you look bug
https://bugzilla.redhat.com/show_bug.cgi?id=815515 Another IPA user
contributed a secure DUA Profile which is quite complete.
