meta backend subtree directive ignored by conversion to cn=config

Hi all, I realized that the subtree-include directives I use in my meta backend are not converted at all to cn=config. I cannot find them in cn=config tree.

Listing linux users
by Thiago Parolin 20 Feb '13

20 Feb '13

Hi all. My scenario is: openldap/samba pdc server for authenticating Windows and Linux. I need to know when a user, from Linux clients, logs in and out from the system. If some problem occurs, i need to know who was logged, in particular computer, in that time. With windows computers, the "last" bash command (in server) gave me the information needed, but with linux clients i don't know what i have to do. They are not listed with "last" command. I don't want to redirect all auth logs from clients to my server. It probably will overload my server. There are some way to do this?

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.

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?
