[Fedora-directory-users] Using certs from MS CA server

Hello,
I have FDS 1.0.4 running using an SSL certificate generated by an Microsoft
windows 2003 CA server.
I choose this method as opposed to the setupssl.sh script from the wiki
because I have read in the list archives that it is the best way to avoid
trust issues when setting up PassSync over SSL between FDS and AD. I'm
having a hard time finding references for configuring this properly and I
know very little about SSL certificates so I'm making some guesses and
likely missing a crucial step or two.
The problem is that when trying to bind to the FDS using SSL I get
certificate verification errors.
> # ldapsearch -x -H ldaps://localhost/
> ldap_bind: Can't contact LDAP server (-1)
> additional info: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Here's how I set up the certificates...
1. Generated a CSR using the FDS console wizard and submitted it to the MS
CA.
2. Imported the CA certificate (called "it") and the signed "server-cert"
resulting from step 1 from the MS CA using the FDS admin console.
3. Enabled SSL (port 636) in the directory server using server-cert from
step 1.
I used certutil to display the list of certificates in the FDS cert db.
> [alias]# ../shared/bin/certutil -L -d . -P slapd-<instance>-
> server-cert u,u,u
> it CT,,
Then verified that "server-cert" was considered valid.
> [alias]# ../shared/bin/certutil -V -n server-cert -e -u V -d . -P
slapd-<instance>-
> Enter Password or Pin for "NSS Certificate DB":
> certutil-bin: certificate is valid
I also verified that that I can connect using openssl client.
> # openssl s_client -connect localhost:636 -showcerts -CAfile
/path/to/it_ca.crt
--snip--
> Verify return code: 0 (ok)
> ---
Any hints as to what I might be doing wrong are greatly appreciated.
Thanks,
-Jake
