Re: Reg OpenLdap on Ubuntu


I did run some openssl commands and here is what I saw.

# openssl s_client -connect <ldap server ip>:636

verify error:num=20:unable to get local issuer certificate
verify return:1

verify error:num=21:unable to verify the first certificate
verify return:1

No client certificate CA names sent
SSL handshake has read 1162 bytes and written 450 bytes
Verify return code: 21 (unable to verify the first certificate)

The same thing I got when I ran the command on local ldap server too.

Are the certificates not OK? If this is so, how am I able to run ldapsearch with "-ZZ" option.

Regarding the apache issue, as I expected, fingers raised towards the certificate file even if I have clarified that the same certificate works fine with the local client (installed along with the server).

Is there any way so as to prove that certificate file is Ok?

I think I am supposed to provide the bind DN with "-D" option i.e. cn=admin,dc=ldap-company,dc=com.

With this value, it works fine.

Sorry for the mistake.

Reg Apache issue, I will post it here once it is solved.

Hi Dieter,

I will try to look it from a different angle. Once I am able to solve it, I will post it here.

I have one more query.

On my server, I am able to get the result by :

# ldapsearch -d8 -H ldaps://ldap-company.com -b dc=ldap-company,dc=com uid=asimananda
SASL/DIGEST-MD5 authentication started
Please enter your password:


But the following query doesn't show any result and throws error.

# ldapsearch -d8 -H ldaps://ldap-company.com -D dc=ldap-company,dc=com uid=asimananda -W
Enter LDAP Password:
ldap_bind: Invalid credentials (49)

Does this mean that I have still some configuration to do?

Please comment.

As I mentioned many times, this topip is neither OpenLDAP nor Ubuntu
related, it is just a question of how to properly set up Apache on Sun
Solaris 10.
Did you configure mod_auth_ldap and mod_ldap to use TLS?
There are two sources of information, Sun Bigadmin and Apache
documentation. Lot of documentation is referring to *.der or cert7.db
files, note that OpenLDAP only handles *.pem files. For mor
information on this topic read openssl documentation.
