Write to Disk?
by Golden Butler 06 Oct '06

06 Oct '06

Yesterday, we lost power due to an power outage and our openldap server went down. When power was restored and the server was back up, I noticed that a lot of entries that I have entered over a period of time (about two months) were gone! Is there a way to ensure that openldap write changes to the database to disk instantly? Any help or suggestions would be greatly appreciated, thanks. - Golden

Well, nothing, because I'm going to an LDAP server on another system. But I did finally get it working late last night/early this morning thanks to a couple tips I received here. The big issue was making sure I was using the "-H" option with a URI rather than using a combination of the "-p" and "-h" options in ldapsearch. But thanks for the offer to help, and a big thanks to those who recommended the solution to me! ------ +-------------------------------+----------------------------------------+ | Dan O'Reilly | "There are 10 types of people in this | | Principal Engineer | world: those who understand binary | | Process Software | and those who don't." | | http://www.process.com | | +-------------------------------+----------------------------------------+

How do I fix issues of really poor performance
by Rob Tanner 06 Oct '06

06 Oct '06

Hi, I'm replacing an old Netscape server running on a 296 MHz dual processor Solaris 5.7 (sun4u sparc) box with OpenLDAP 2.3.27 running on a single 2.4GHz processor Intel box running Fedora Core 4. I have duplicated one of my hierarchies -- approx 9000 entries. There is an index on an attribute called deptaffiliationcodes (on both systems) which I'm using as a search filter to make sure everything is working. Dumping the results to /dev/null, a search on the Netscape server takes typically 35 milliseconds to complete. The exact same search on the OpenLDAP server takes between 2.5 to 3.5 seconds. And that's way too slow for me to put the OpenLDAP server into production. I am using the bdb backend and the example DB_CONFIG file which sets the cache size to 268435456 bytes, which is bigger than the actual size of dn2id.bdb and id2entry.bdb combined (about 16Mb). What other factors can affect performance? Any help would be most appreciated. Thanks, Rob -- Rob Tanner UNIX Services Manager Linfield College, McMinnville OR

need transactions in openldap 2.3.*
by Dmitriy Kirhlarov 05 Oct '06

05 Oct '06

Hi, list Now we are using ldap-tree for auth several services on many hosts. We have two types of admins (admin1 and admin2 roles) and I want separate permissions: - admin1 can edit cn=usergroup1, but can't edit cn=usergroup2. - admin2 can edit both. (I know how I can do it). Next. User can be registered in both groups, or just in one. We are developing our own ldap admin-tool for usermanagement. When user gone, we removing his id from all groups and lock his account. Usualy, this is work for admin1. We need this behavior of our tool: If we can't remove user id from some group (inusufficient access), we do nothing. Just answer to admin1 "You can't remove user from group2 -- ask admin2". For this behavior we need either transactions or some easy way to check our access rights for all entries which we want to modify. Afaik, transactions are not feasible for our case. What about checking access rights on client side without performing modification itself?

hdb and subtree deletion
by johan.jonemo＠hep.lu.se 05 Oct '06

05 Oct '06

After having seen Howard Chu's slides about back-hdb from March 21, 2003, I have the impression that deleting a subtree can be done in O(constant) time. I haven't however understood how. Question: How does one delete a subtree in a hdb directory? I have tried deleting the top node, but the server doesn't let me do that. On a slightly related note. I think many users would like the "OpenLDAP Software Administrator's Guide" to contain sections about the different modules (both backends and overlays) like it does about proxy-cache. I think it would be a great help even if they were ever so short. This is of course not said to critisize the guide as it stands today but rather as a suggestion for a contribution to anyone who feel they have the prerequisite knowledge. Johan Jönemo

How to migrate MS - Active Directory to Linux OpenLDAP
by Raghu Ni 04 Oct '06

04 Oct '06

Hi, We are trying into migrate from Active Directory to Open LDAP. But, we getting problems with Schema Attributes. Can any one help us in this ? Here, migrating means "NOT delegating Active Directory Services to Open LDAP" or/and authenticating Linux system with micro soft Active Directory services. We are looking for a solution, throgh which we can replace the existing Active Directory Service with Open LDAP server in linux ( We want import schems in Active Direcotory into Open LDAP). We know that, schema attributes for both the services are different. RaghuNi.
