Search filter for numbers
by Florian Götz 30 Sep '09

30 Sep '09

Hi everbody, I tried to create a dynamic group with dynlist and got a problem with a search filter. I searched the net for a solution, but found nothing that fits. I want to collect all people thet have a common attribute (attributA=X), but only people that have a uid that isn´t a number. We got people with uids similar to their last name (Meier, Müller, Schmidt) and Users that got a number as uid (123456). I tried a filter like: ldap:///ou=users,dc=example,dc=de?uid?sub?(&(attributeA=X)(!(uid=[0-9]*))) but that doesn´t work. A solution like: ldap:///ou=users,dc=example,dc=de?uid?sub?(&(attributeA=X)(!(uid=0*))(! (uid=1*))(!(uid=2*))(!(uid=3*)).....) works, but there must be a more elegant way to do this....right?

Unable to bind to active directory using TLS
by Harish Chakravarthy 29 Sep '09

29 Sep '09

Hello Everyone, Greetings. I am unable to bind to active directory using TLS. I get the following error while executing my script via the browser *PHP Warning: ldap_start_tls() [<a href='function.ldap-start-tls'>function.ldap-start-tls</a>]: Unable to start TLS: Connect error* The same script when executed from the command line works!. I have compiled PHP with flags --with-ldap --with-ldap-sasl --with-openssl . Can you help me further trouble shoot this problem?. Thanks Harish

Memberof overlay
by Kristian Berg 25 Sep '09

25 Sep '09

Hi I've shifted through the mailinglist archive in search of an answear to how one combines posixAccount with posixGroup for filtering, with the memberof overlay. The only answear I found, was that it wasn't possible. What I've tried was adding: overlay memberof memberof-group-oc posixGroup memberof-member-ad memberUid Which doesn't work. I get the following error message: /etc/openldap2.4/slapd.conf: line 173: member attribute="memberUid" must either have DN (1.3.6.1.4.1.1466.115.121.1.12) or nameUID (1.3.6.1.4.1.1466.115.121.1.34) syntax. According to earlier mailinglist posts, memberUid can't be used with memberof. The other solution that crossed my mind was adding a member-attribute in the posixGroup which is linked with the posixAccount dn, whenever I add a memberUid to the group. Although I haven't tested it yet, as my schema-fu is limited. This seems like the wrong approach though. What I want to do is using a ldap query filter to check if a posixAccount is member of a group with the same name as the server. Ie: retreiving all valid accounts for that particular server with (&(objectClass=posixAccount)(memberof=cn=servername,ou=group,dc=base)). This is with standard ldap on AIX as the client and openldap 2.4.18 as the server. Linux clients and hp-ux clients also connect to this ldap-server though, so the options regarding layout of the tree is limited. So may questions to you, dear internett mailinglist heroes, is: * Is there an easy way to combine posixAccount with posixGroup? * Is the hard way feasiable if not? * Are some of you using some better way of managing logins on aix with a ldap-server shared with operating system logins? -- Kristian Berg

Limiting finger lookup access on Linux
by Rex Roof 24 Sep '09

24 Sep '09

I have some linux machines that I have configured for student access. We are authenticating against our OpenLDAP tree and limiting which users have access via an LDAP groupOfNames. This is all working perfectly. This is the problem I am having. Any user with access to the system can run the /usr/bin/finger command and do a name search against our entire LDAP tree. I would like to limit the info available via finger to just the users that have access to any particular machine. How can this be controlled? -Rex

It indeed was a great conference, thanks for organizing it.

OpenLDAP doesn't just scale up to massive multi-processor deployments, it also works well at the smallest of scales.

Much thanks for sharing your experience and validating the deployment openLDAP+Samba/PDC in a virtual environment.

bdb checkpoints
by Oliver Henriot 24 Sep '09

24 Sep '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list users, I'm trying to get my DB_CONFIG file sorted out and I'm getting confused. If I follow the documentation available on zytrax.com (http://www.zytrax.com/books/ldap/ch6/bdb.html#db-config), if I have a DB_CONFIG file it should contain a txn_checkpoint directive instead of the checkpoint directive in slapd.conf file which indeed does nothing no matter if I change it or not. But if I put a txn_checkpoint in the DB_CONFIG file I get a "unrecognized name-value pair: txn_checkpoint" error and everything dies miserably. So, as Howard suggests (http://www.openldap.org/lists/openldap-software/200605/msg00091.html), I set off on a quest to read the BerkeleyDB documentation. I'm finding reading it not very useful for several reasons. Firstly txn_checkpoint directive sometimes occurs (http://www.oracle.com/technology/documentation/berkeley-db/db/programmer_re… so at least version 3.1, and up?, should understand txn_checkpoint) and sometimes not (http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference…). Secondly, there is scarce, if any, reference to the versions of BDB concerned in the documentation I have found and now I have spent an awful amount time (well, ten minutes maybe) trying to find out exactly which version of BDB I have I'd like to make some intelligent use of that information if at all possible. Well, I'm lost. The only thing I've found is a gigabyte of bdb logs created when I populate my directory wich are not removed by dbconfig set_flags DB_LOG_AUTOREMOVE, and even more as my directory lives it life (several gigabytes after a week or two). So I'd like to reduce their volume if at all possible rather than having to regularly remove them using slapd_db_archive manually. So, what's the story with BDB transaction checkpoint logs? How can I get this mess sorted out? I'm using Openldap 2.3.43-3.el5 with BDB 4.3.29 on CentOS 5.3. Thanks.
