ldapsearch question
by Benin Technologies 30 Jan '13

30 Jan '13

Hi, I was wondering if the following search can be done. Let's say I have this tree : ---> dc=com | |-->dc=mycompany | | -->cn=Jane Doe | |-- objectClass=inetOrgPerson |-- cn=Jane Doe |-- mobile : 11223344 |--> cn=secretary | |--objectClass=organizationalRole |--cn=secretary |--telephoneNumber = 12345678 I'd like to return, in a SINGLE search, something like : cn : Jane Doe - mobile : 11223344 - telephoneNumber : 12345678 In other words, I'd like the search to return the attribute telephoneNumber AS an attribute of Jane Doe, and not as an attribute of Jane Doe --> cn=secretary Ben

ldapsearch trying to use SASL
by Scott Classen 29 Jan '13

29 Jan '13

Hello, I have a script which checks for the existence of an email address in my LDAP directory. the relevant line is: ldapsearch -D "uid=nss,dc=bah,dc=com" -w mypassword -b "ou=People,dc=blah,dc=com" uid=bobthebuilder mail If I run this script as the root or tomcat user it works as expected and returns the mail attribute. If this script is called from Apache Tomcat webapp (running as the tomcat user). I receive the following errors in my slapd.log file: Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 fd=26 ACCEPT from IP=131.1.2.3:50230 (IP=0.0.0.0:389) Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SRCH base="" scope=0 deref=0 filter="(objectClass=*)" Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SRCH attr=supportedSASLMechanisms Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SEARCH RESULT tag=101 err=0 nentries=1 text= Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=1 BIND dn="uid=nss,dc=bah,dc=com" method=163 Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=1 RESULT tag=97 err=14 text=SASL(0): successful result: security flags do not match required Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=2 BIND dn="uid=nss,dc=bah,dc=com" method=163 Jan 29 13:59:29 bl1 slapd[3783]: SASL [conn=247839] Failure: no secret in database Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=2 RESULT tag=97 err=49 text=SASL(-13): user not found: no secret in database Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 fd=26 closed (connection lost) I don't understand why the ldapsearch is searching for attr=supportedSASLMechanisms when invoked from within a Tomcat Webapp, but works fine when invoked from a c shell. Any ideas? Your help is greatly appreciated. Scott

Re: replication between a back-sql master and back-hdb slave
by Benin Technologies 29 Jan '13

29 Jan '13

ok thanks I found that in the mailing list archive, dating back from 2007 (http://www.openldap.org/lists/openldap-software/200708/msg00015.html) Indeed back-sql was intended to loosely support acting as a syncrepl provider (limited to refreshOnly), but it's currently broken, and it's never been fixed (mostly due to lack of interest). Patches (or sponsorships) are welcome. Ing. Pierangelo Masarati OpenLDAP Core Team So I was wondering if it has been fix since... > your question is, can I use back-sql as syncperov.

Usage of groups in an access control
by Marco de Booij 28 Jan '13

28 Jan '13

I use openLDAP already for years to store my users so I have to define them only once. The users can logon to both Linux and Windows (samba). Now I want to add address-books and manage the access rights. I have a problem with the usage of groups in an access control. I want to gave addressbooks in my LDAP but they should not be accessible by everybody. I used http://www.openldap.org/faq/data/cache/52.html to configure openLDAP but it does not seem to work. I have created a group like this: dn: cn=abk-admin,ou=Roles,dc=example,dc=com objectClass: groupOfNames member: cn=My ENTRY,ou=People,dc=example,dc=com cn: abk-admin and an address-book like this: dn: ou=abk1,ou=Addressbooks,dc=example,dc=com ou: abk1 objectClass: organizationalUnit objectClass: top (Both entries are output of slapcat. I did not put in the attributes like creatorsName and entryUUID) In the slapd:conf I have the following access rules: access to attrs=userPassword,sambaNTPassword,sambaLMPassword,sambaPwdMustChange,sambaPwdLastSet by dn="cn=admin,dc=example,dc=com" write by dn="cn=proxyuser,dc=example,dc=com" read by anonymous auth by self write by * none access to attrs=shadowLastChange,shadowMax by self write by * read access to dn.base="" by * read access to * by dn="cn=admin,dc=example,dc=com" write by * read access to dn.children="ou=abk1,ou=Addressbooks,dc=example,dc=com" by dn="cn=admin,dc=example,dc=com" write by groupOfNames="cn=abk-admin,ou=Roles,dc=example,dc=com" write by groupOfNames="cn=abk-user,ou=Roles,dc=example,dc=com" read by * none I searched around and changed dn.children by dn.subtree and dn.one but the result is the same. I can read the entries but I cannot insert or delete an entry. I can only do this with admin but only if the line for admin is defined. What did I do wrong or understood wrong? I tried to find the answer on the internet but was not able :( OpenLDAP: slapd 2.4.23 (Jun 16 2011 02:53:39) Debian 6.0.6 Regards, Marco

Re: Permissions, users, startup when install from source

Thus, as best I can tell, it is indeed included. My "surprised" comment is in reference to the fact that the default build of OpenLDAP only supports SHA1, which is widely regarded as deprecated. Why hasn't the sha2 module been migrated out of the contrib directory is what I am getting at (which commonly requires situations like this -- forcing people who wouldn't otherwise do so to install from source just to obtain this feature). One could argue that situations like this contribute to the lack of adoption of stronger password schemes in general. Something of an off-topic tangent. > If you are using RHEL or CentOS, you may be interested in > <http://ltb-project.org/wiki/download#openldap> Great. I will investigate. Does anyone else know of any yum-compatible repos that have a sha2-enabled OpenLDAP build in them? Anyone know anything about the OpenLDAP packages in RepoForge? I actually only assumed without testing that the OpenLDAP package in the CentOS base repo doesn't have the sha2 module compiled in. I should go back and check that assumption. Also, reflecting on the installation of the sha2 module, it occurs to me that short of the CentOS repo package already having sha2 compiled in, the best course of action is probably to compile only the sha2 module and use it with the CentOS package --- including the module in the slapd configuration seems to be the extent of integration, so that should work, no? If so, I think this would be the best option. >> After installation, what is commonly done in this regard?

I don't have needs that are much different than anyone else. I naively assume slapd should generally not be run as root. In that case, is creating a ldap user/group and chowning the openldap-data directory the only things to do? >> Then what do people use for auto-starting the software (presumably >> with -u ldap -g ldap) in a RedHat environment? > > I wrote my own startup script that works with chkconfig. > <http://linuxcommand.org/man_pages/chkconfig8.html> I'm looking for anyone who wants to share such scripts.

Are there any disadvantages, like using more RAM, or other things to care..? Thanks, Meike
