How to search for all the dynamic groups a member belongs to?
by Carlos Santos 20 Feb '13

20 Feb '13

Hello to all of you, So, the situation is the following: I have a dynamic group (objectClass: groupOfURLs) and on my ldap filter I fetch the users UID. When I access the content of the group, there are a set of members there, one of them is testUser1, but when I search for (&(objectClass=groupOfURLs)(uid=testUser1)) the search result is empty. However when I search for an attribute which is native to the class, such as owner, the search returns the group. Is it possible for an ldap search to return the dynamic groups a user belongs to? -- cumprimentos, Carlos Santos

paged search fails through proxy
by Eimar Koort 20 Feb '13

20 Feb '13

Hi, I'm a bit in dead end. Scenario: Active Direcotory & openldap (2.4.33) proxy. Paged search through proxy is not working. I'm not sure about this OID "1.2.840.113556.1.4.1339". OpenLdap ldap.h tells that this oid is LDAP_CONTROL_X_DOMAIN_SCOPE. According to O'Reilly AD cookbook: "No referrals generated" with longer description "Informs the server not to generate any referrals in a search response". May this be the reason for paged search to fail? Same query runs without any problems directly within Active Directory domain controller's. As i read from google, it should be possible to make paged search work, but i can't figure it out how. eimar@box: /tmp > ldapsearch -LLL -H ldaps://olp-test.example.ee -P 3 -E pr=500/noprompt -D "CN=ldap-auth,CN=Users,DC=example,DC=ee" -W -b "ou=workers,dc=example,dc=ee" "(objectClass=person)" samaccountname -s sub > results.txt Enter LDAP Password: Size limit exceeded (4) eimar@box: /tmp > grep dn\: results.txt | wc -l 1000 which is the default search limit in AD.

19 Feb '13

Hi all, I'm trying to build OpenLDAP enabling the GSSAPI module, but I can't find any reference on that in the configure file. I'm doing that because I'm writing a client program that want to login to a Windows AD via kerberos. Any help is appreciated.

ldapi without TLS and ldap with TLS?
by Patrick Lists 19 Feb '13

Hi, I'm tying achieve the following with OpenLDAP RE24 from last week: Connections on ldapi:/// are plain text and ldap connections require TLS with client cert auth.

Problem in user authentication with LDAP + SSSD

Where is the TLSCertificateFile in cn=config?
by Sascha Ziemann 18 Feb '13

18 Feb '13

I am looking for the right DN in the cn=config tree for the following options of the legacy slapd.conf file: TLSCertificateFile /path/to/server-certificate.pem TLSCertificateKeyFile /path/to/private-key.pem TLSCACertificateFile /path/to/CA-certificates Where do I have to put the path names? Maybe someone can update the FAQ: http://www.openldap.org/faq/data/cache/185.html

User Private Groups
by Omar Hijab 17 Feb '13

17 Feb '13

Hello, Does openLDAP support User Private Groups by having memberOf return a fake self-group through some rewriting rule? Our campus has a SUN LDAP for user data that is not under our control. Our Mac and Linux clients use it for authentication. This server does not provide group management as a service. Because of this, we set up a separate openLDAP server to create/store groups. With clients bound to both servers, this works seamlessly. Because of this, we want our server to respond to memberOf queries with a fake private self-group in addition to legitimate groups the user is in, this without creating and storing private groups on our server. Is this do-able?
