Hi all,
I'm trying to get SASL working with OpenLDAP + TLS. I got it
working without TLS with these settings:
slapd.conf:
----------
TLSCipherSuite HIGH:MEDIUM:+SSLv3
TLSCACertificateFile /var/myCA/cacert.crt
TLSCertificateFile /var/myCA/server_crt.pem
TLSCertificateKeyFile /var/myCA/server_key.pem
# Use the following if client authentication is required
#TLSVerifyClient demand
# ... or not desired at all
TLSVerifyClient never
What '-h' parameter are you starting slapd with?
saslauthd.conf:
ldap_servers: ldaps://localhost
ldap_bind_dn: cn=admin,dc=abc,dc=com
ldap_bind_pw: 123456789
ldap_search_base: dc=abc,dc=com
This works great with testsaslauthd:
root@ldap:/usr/local/sasl2/sbin# ./testsaslauthd -u khanhnq
-p 1234560:
OK "Success."
However, when I add these lines to saslauthd.conf, it fails:
ldap_start_tls: yes
ldap_tls_cacert_dir: /var/myCA
ldap_tls_cacert_file: /var/myCA/cacert.crt
ldap_tls_cert: /var/myCA/server_crt.pem
ldap_tls_key: /var/myCA/server_key.pem
You should change:
ldap_servers: ldaps://localhost
to
ldap_servers: ldap://localhost
when using starttls, and you should verify that you're starting slapd with
'ldap:///' as one of your -h URLs.
In your slapd config, you specified 'TLSVerifyClient never' (no client
authentication), but in your saslauthd.conf, you've specified a cert and a
key. Do you intend to do client TLS authentication? If not, those two lines
should not be needed.
For more information, see 'saslauthd/LDAP_SASLAUTHD' within the cyrus sasl
source, and slapd.conf(5).
root@ldap:/usr/local/sasl2/sbin# ./testsaslauthd -u khanhnq -p 123456

When i checked /var/log/auth.log, i got a messages:
