SSL Cert Issue

[John Mancuso]

Two questions:

1. I have generated self-signed ssl/ca certs trying both the
"certutil" method from the redhat doc and also the standard "openssl
x509 req -new" method. After installing the certs and enabling secure
ldaps replication both result in

slapi_ldap_bind - Error: could not send bind request for id
[cn=replication manager,cn=config] mech [SIMPLE]: error 81 (Can't
contact LDAP server) -8172 (Peer's certificate issuer has been marked
as not trusted by the user.) 11 (Resource temporarily unavailable)

Is there a known issue with self-signed certs?

2. If there is an issue with the above, we may end up purchasing a
wildcard cert for replicating across subdomains. I know in the HTML
world some web browsers complain about ssl wildcard certs across
subdomains. Any possible issues with this approach?

ldaps://supplier_ldap.mycompany.com----> ldaps://consumer_ldap.dev.mycompany.com

You need to create your own CA Cert, sign your cert with that CA Cert, 
and import the CA cert into the certutil store.

You also want to put the CA public cert into /etc/openldap/certs so the 
openldap tools will use it.

There are a few guides on the internet for creating your own CA.  I know 
Fedora 13 comes with its own CA tool.  I personally use tinyca.

No, they work fine. Did you add the CA certificate that signed the 
server certificate as well?

You can verify that the certificate is ok on the server with:

certutil -V -u V -d /etc/dirsrv/slapd-<YOUR_INSTANCE>

You are probably just missing the CA certificate. If you have it in PEM 
format you can add it via the command-line with:

certutil -A -d /etc/dirsrv/slapd-<YOUR_INSTANCE> -n 'Your CA' -t CT,, -a 
< /path/to/ca.pem

The 'Your CA' here is the nickname of the CA certificate. It is how it 
will appear in the DS console and using certutil -L. Pick something 
meaningful to you.

A wildcard cert will work but its probably overkill to buy one just for 
this purpose. self-signed certificates will work fine.

I followed the exact procedure below numerous times with the same
frustrating error:

http://www.redhat.com/docs/manuals/dir-server/ag/8.0/Managing_SSL-Using_c...

!481 $ openssl verify cacert_core.asc
cacert_core.asc: /DC=tv/DC=freewheel/CN=CA cert
error 18 at 0 depth lookup:self signed certificate
OK

!482 $ openssl verify cacert_PEKdev020.asc
cacert_PEKdev020.asc: /DC=tv/DC=freewheel/CN=CA cert
error 18 at 0 depth lookup:self signed certificate
OK

!474 $ certutil -V -u V -d . -n "Core CA certificate"
certutil: certificate is valid

!476 $ certutil -V -u V -d . -n "Core Server-Cert"
certutil: certificate is valid

I also imported the consumers CA cert into the supplier ... this is
correct? I tried only importing the suppliers CA cert before with the
same issue (trying everything here!)

This looks strange though (why the duplicate cert):

!478 $ certutil -d . -L

Ok, I think I know what you're seeing. Did you do the same procedure on 
both the master and the replica?

If you did then you created two separate CAs that know nothing about 
each other and don't trust one another.

You probably just want one CA in this case so I'd just pick either the 
master or replica and issue another server certificate from it:

certutil -S -n "Replica-Cert" -s "cn=FQDN" -c "CA
certificate" -t 
"u,u,u" -m 1001 -v 120 -d . -k rsa -g 1024 -f /tmp/pwdfile

Then use pk12util to create a PKCS#12 file containing the cert and 
private key:

pk12util -o replica.p12 -d . -n Replica-Cert

Ship this over to the replica and import it with:

pk12util -i replica.p12 -d .

The CA cert should be included in the PKCS#12 file but if it isn't 
you'll need to grab it from the master and install it on the replica.

That's what it was! thanks. Unfortunately going across subdomains was a no go :

-12276 (Unable to communicate securely with peer: requested domain
name does not match the server's certificate.

I tried to generate a self signed wildcard (cn=*.mycompany.com) but no
luck there. Thanks anyways!

Use SubjectAltName instead of wildcards -
