Turn off anonymous bind

[David Hoskinson]

We want to restrict all queries to authenticated queries.  As our system sits now I can
anonymously query and return ntlmpassword and see the hash as well as most other entries. 
We would like this to not be the case, and requires directory manager and pass or a
similar approved user to do ldap queries.

I have set nslapd-allow-anonymous-access to off in  advanced properties for config, and
added the binddn string and bindpw string to /etc/ldap.conf on the 389 server machine. 
When I try to log back in, I get password authentication failed, please verify that the
username and password are correct.  If I turn the setting back to on, it works again.

Am I missing something... or is this not the correct method to achieve my goal.

Thanks.

so we should have under cn=config
nsslapd-allow-anonymous-access: off
nsslapd-allow-unauthenticated-binds: off
( see
http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.2/html/Admin...
)
Review the ns-slapd error log, may be it is falling back to anonymous 
for some reason.
Try a getent passwd from that client to see if it is working as 
expected, and try to manually run a ldapsearch, binding as the binddn 
with bindpw specified in in the nss_ldap config file, for a given user, 
and then another search specifying the ntlmpassword attribute for a 
given user.
If not working, review the ACI for ntlmpassword in that suffix.

Forgot to mention that this machine uses ssl encryption if that makes any difference.  And
settings match the link below.  Can't test getent passwd or ldapsearch as I can't
log back in unless I put settings back.

Did you verify that you can use the binddn and bindpw to successfully 
bind to the directory server?

Did you check the directory server access log to see what the client is 
doing when getent fails?
