Fedora directory users - Jun 2006 - PassSync problems (Peer''s Certificate issuer is not recognized)

I have followed RHDS Admin guide and Howto:WindowsSync several times, but I keep
getting this error:

ldapsearch -Z -P . -h ad-host -p 636 -D
"cn=administrator,cn=users,dc=xxx,dc=xxx,dc=xxx" -w - -s base -b
"" "objectclass=*" -v

Enter bind password: 
ldapsearch: started Tue Jun  6 11:28:46 2006
 
ldap_init( ad-host, 636 )
ldaptool_getcertpath -- .
ldaptool_getkeypath -- .
ldaptool_getmodpath -- (null)
ldaptool_getdonglefilename -- (null)
ldap_simple_bind: Can''t contact LDAP server
        SSL error -8179 (Peer''s Certificate issuer is not recognized.)

I can search FDS over SSL. I have exported the Server-Cert from FDS and imported
it into AD (PassSync).

I have changed the trust attributes per the Howto, eventhough the attributes
only change to "CT,C,C (CA certificate)" and "Pu,Pu,Pu
Server-Cert"
