RE: TLS with multiple LDAP servers

[Jon C Kidder <jckidder@aep.com>]

The methods you use to successfully complete a TLS handshake are completely dependent upon the methods you choose to implement "fail-over" to your second LDAP server.  Will you be using a common name and virtual IP? Will you be using a common virtual name (DNS round robin or intelligent name server)? Will your client handle fail-over internally and connect directly to each server?

Once we have the details around your fail-over solution we can provide more advice on methods for handling the host name validation portion of your TLS handshake.

Hi,
I have two LDAP servers in master-slave
ldap1.domain.com - master
ldap2.domain.com - slave
These servers got different ip addresses and are hosted on different servers But I want to enable TLS connection with clients.
So can I create a unique certificate that I put on both servers and the client will use one unique certificate to connect to server "ldap1" or "ldap2" if the first one is down.

If not, how should I do?
I did a search and I found that I can use subjectAltNames or wildcard certificat.

Thanks
