Re: OpenLDAP freezes and doesn't respond

No I don't use pass through authentication. Anyway, I'll check the
cyrus-sasl related rpm's just in case
there's an available update or patch from Red Hat ..

Is time in sync between the servers?
What versions are you dealing with?

Syncrepl can't start ssl session because of refused 'client' certificate
by Thibault Le Meur
Hello,
I'm trying to upgrade an openLdap server from Fedora Core 13
(openldap-servers-2.4.21-11) to Redhat Enterprise 6
(openldap-servers-2.4.23-15.el6.x86_64).
In this new setup, my local bdb backend works: I can query the LDAP
server on this backend using an "ldaps://" connection (it is using a
server certificate).
However, the Syncrepl replication process fails to establish the
"ldaps://" session to my syncrepl-providers.
Indeed, the TLS layer complains that my _server's certificate_ isn't a
valid _client certificate_ (with error 8101 -
SEC_ERROR_INADEQUATE_CERT_TYPE): but I don't want client-side
authentication!
In the past syncrepl didn't try to use the server certificate as a
client certificate, and I haven't seen any reference to this in the
documentation.
I first thought it could have been related to ITS#6791 but I don't think
so anymore because it only affects Syncrepl.
Do you think I've missed something in the setup?
Thanks in advance,
Thibault

Locking SAMBA ccounts with LDAP backend
by Michael Starling
Hello. Is it possible to have SAMBA respect PAM so that when an LDAP
accounts gets locked out the SAMBA account simultaneously gets locked
out as well?
All my windows clients are either 2003 or 2008 servers
and if I understand the blurbs below in the samba man page, the
"encrypted password" directive must be set to yes in order for Windows
machines to authenticate against SAMBA, however if "encrypted passwords"
is set to yes then SAMBA will ignore the directive "obey pam
restrictions". Is there any way around this?
I'm sure you'll let me know if this question is better suited for the samba lists.
OS: RHEL 5.5 x64
samba3x-3.5.4-0.70.el5_6.1
openldap-2.3.43-12.el5_6.7
obey pam restrictions (G)
When Samba 3.0 is configured to enable PAM support (i.e. --with-pam),
this parameter will control whether or not Samba should obey PAM´s
account and
session management directives. The default
behavior is to use PAM for clear text authentication only and to ignore
any account or session
management. Note that Samba always ignores PAM for authentication in the case of encrypt passwords = yes. The reason is that PAM modules cannot
support the challenge/response authentication mechanism needed in the presence of SMB password encryption.
encrypt passwords (G)
This boolean controls whether encrypted passwords will be negotiated
with the client. Note that Windows NT 4.0 SP3 and above and also Windows
98
will by default expect encrypted passwords unless a
registry entry is changed. To use encrypted passwords in Samba see the
chapter "User Database"
in the Samba HOWTO Collection.
MS
Windows clients that expect Microsoft encrypted passwords and that do
not have plain text password support enabled will be able to connect
only
to a Samba server that has encrypted password support
enabled and for which the user accounts have a valid encrypted password. Refer to the
smbpasswd command man page for information regarding the creation of encrypted passwords for user accounts.
The use of plain text passwords is NOT advised as support for this
feature is no longer maintained in Microsoft Windows products. If you
want to use
plain text passwords you must set this parameter to no.
In order for encrypted passwords to work correctly smbd(8) must either
have access to a local smbpasswd(5) file (see the smbpasswd(8) program
for
information on how to set up and maintain this file),
or set the security = [server|domain|ads] parameter which causes smbd to
authenticate against
another server.

getent passwd always return 1065 users
by Oliver Schulze L.
Hi,
I have a openldap server in RHEL4 and after the latest update I can only
get 1065 users from the command getent passwd:
getent passwd | wc -l
I have like 15k users. Slapcat list them all.
Where should I look for a solution? In the cache size of the DBD, in
/etc/ldap.conf, in slapd.conf?
Many thanks
Oliver

Have you tried raising the loglevel?
Are the schemas the same between the servers?
Is time in sync between the servers?
What versions are you dealing with?
You don't provide a lot of info and most of us are not clairvoyant....

whose responsability
by Friedrich Locke
Hi,
i have installed and configured openldap and so far, so good. But i
have a simple doubt.
Up to now, all users i have added to the ldap server have a field:
userPassword: {SASL}user@domain
I am connecting to retrieve the entry attributes with the following command:
ldapsearch -x -w PASSWORD -D uid=user,ou=people,dc=my,dc=domain -b
uid=user,ou=people,dc=my,dc=domain
And everyting works ok.
My doubt is:
who is performing the password checking? The openldap server
daemon (slapd) ou the ldapsearch ?
Thanks in advance.
Regards,
Friedrich

selective services in an LDAP based CAS setup
by Joe Steeve
Hello all,
We are using OpenLDAP to provide a common authentication back-end for
mail, samba and a couple of web-applications.
We want to selectively enable/disable services (mail, samba, etc.) for
some users based on management policy.
What is the best way to do it using LDAP?
Regards,
Joe
