idletimeout and writetimeout
by Tianyin Xu 27 Mar '12

27 Mar '12

Hi, Who can kindly tell me what are the two directives "idletimeout" and "writetimeout" used for? I do appreciate if someone can give me some sample examples. I set the values of the two configurations to be very small but no connections are terminated. :-( Thanks in advance! Tianyin -- Tianyin XU, http://cseweb.ucsd.edu/~tixu/

usage of slapadd with replication/option -w
by frank.offermanns＠caseris.de 26 Mar '12

26 Mar '12

Hi all, at the end of the thread "Re: delta-syncrepl and mirrormode problem (2.4.29 and 2.4.30)/ slapadd Usage" I already asked some questions. But probably due to the wrong threadname I got no answer. So here again with a clearer threadname: Multimaster only works when slapdadd for initial filling is used with -w Is this a bug or does it work as designed? If it works as designed maybe the manualpage for slapadd should be more clearly that when you work with replication you always have to use the -w option. Wouldn't it be helpfull if slapadd internally always use the -w option or are there cases in which this option could be harmfull? What happens if I use -w and have no replication configured? Regards, Frank

syncrepl and structuralObjectClass operational attribute
by Jehan PROCACCIA 26 Mar '12

26 Mar '12

Hello I installed a new openldap replica (openldap-servers-2.4.23-20.el6.i686) , with a partial replication enabled by restricting certain branches/attributes to the binddn account that replicate from the master. However, on some operation (modify userPassword for example) the modification fails: Mar 22 17:51:20 ldapz2 slapd[24456]: No structuralObjectClass for entry (uid=bde,ou=People,dc=int-evry,dc=fr) Mar 22 17:51:20 ldapz2 slapd[24456]: entry failed schema check: no structuralObjectClass operational attribute Mar 22 17:51:20 ldapz2 slapd[24456]: null_callback : error code 0x50 Mar 22 17:51:20 ldapz2 slapd[24456]: syncrepl_entry: rid=001 be_modify failed (80) Mar 22 17:51:20 ldapz2 slapd[24456]: do_syncrepl: rid=001 rc 80 retrying (9 retries left) what's wrong ? could it be related to the fact that the binddn account cannot read all attributes from the master ? I did checked that he can read userpassword attribute though . is there an ACL to be set to hte replica binddn account to allow him to read operational attributes ? thanks for your help.

Desperate JuniorAdmin needs help ASAP
by Imre Bertalan 26 Mar '12

26 Mar '12

Hello out there! I'm Imre from Hungary and I need some help with LDAP. My main problem is the time. I have 2 weeks to finish a project and a part of it is setting up an LDAP server. To be honest I'll be a big problem if anybody wishes to help me because there is quite a chaos on my head right now and I'm very desperate. I need someone who I can chat with and he/she can show me ( not just write ) how to manage an LDAP server and how to install the client. I wanted to use Webmin because it looks simple enough, but since I don't really getting the point I can't go onward. My suggestion is that someone enters my desktop ( with teamview-er optionally ) and shows me the method on a virtual computer. I would be very, very grateful for you guys. :( PLZ help a poor guy. Best Regards: Imre Bertalan
