    my linux boxes on ldap directory server. If i try to use my test

    configure a self-signed certificate. I''ll not describe all the
tests
    i''ve done, i''ll tell you just the last!! I created my
cacert.pem on
    the ldapserver and i installed from the console. It goes and it''s
    ok. Then i used openssl to generate a private key and a certificate
    request then i signed it. That''s what i did:

       openssl genrsa -out privkey.pem 2048
       openssl req -new -key privkey.pem -out PEM.csr
       openssl ca -cert cacert.pem -in PEM.csr -out cert.pem

      

    I copied cacert.pem, privkey.pem and cert.pem on the client and i
    configured ldap.conf on it:

       URI ldaps://<ldapserver>:636
       BASE ou=UTENTI,o=postel,c=com
       host kingu.postel.com
       TLS_REQCERT allow
       TLS_CHECKPEER yes
       TLS_CACERTDIR /etc/ssl
       TLS_CACERT /etc/ssl/cacert.pem
       TLS_CERT /etc/ssl/cert.pem
       TLS_KEY /etc/ssl/privkey.pem

      

    I activated ssl on my ldap server and i installed my cacert.pem on
    it. i didn''t anything else. I tried also to generate a certificate
    request from directory server and to sign it with my cacert.pem.
    Then i imported it like my server-cert. It imported it but login
    still didn''t go.

Yes. Reading logs it seems login goes ok. But my client can''t really 
login and i don''t know what i can check. Client asks me again for 
password, but i''m sure it''s the right one. Have you any ideas
for
checking something???

Thanks in advance.

Is this /etc/openldap/ldap.conf?  In order to get pam/nss working (I 
assume by "login" you mean login to the operating system) you need to 
configure pam/nss ldap to do TLS, which is the file /etc/ldap.conf, 
which takes the below parameters in slightly different format.

I don''t know if you need TLS_CERT and TLS_KEY - are you attempting to
do
client cert auth - EXTERNAL bind?
