Help: Query unmodified non SSHA userPasswords
by Ulrich Windl 25 Sep '14

25 Sep '14

Hi! I'd like to query userPassword attributes that don't start with "{SSHA", but it seems substring match doesn't work there. An addition I'd like to find those users that didn't change their password since the user was created, i.e. modifyTimestamp=createTimestamp, but I think that's not possible in a search filter as the right of '=' is interpreted literally, right? Any ideas? Regards, Ulrich

Sync Repl - mirror mode - rid=001 LDAP_RES_INTERMEDIATE - REFRESH_DELETE
by Sterling Sahaydak 25 Sep '14

25 Sep '14

I've upgraded my 2 ldap servers to 2.4.39 and have been trying to get mirror mode to work with no luck. I've removed out for now TLS and using ldap:/// The issue I've had since 2.4.23 version and now is "LDAP_RES_INTERMEDIATE - REFRESH_DELETE" Everything else works but have run into this issue that can't resolve. I've looked up in the forum for other references to this, but not seeing a clear resolution. Others, keep getting additional messages beyond this, but mine stops at this. I've tried running also with slapd -h "ldapi:/// ldap:///" -d 7 but getting stuck as well Your help is greatly appreciated!

(ITS#7274) delta-syncrepl MMR infinite loop - like issue?
by Francesco Malvezzi 25 Sep '14

25 Sep '14

During the setup of a mirror mode cluster, I enabled the syncprov after building the mirror. So maybe I run into ITS#7274: http://www.openldap.org/its/index.cgi/Documentation?id=7274;selectid=7274;s… delta-syncrepl fails with: 1) ABANDON log messages on provider; 2) matching "delta-sync lost" log messages on consumer. Do I understand correctly: provider needs contextCSN value for SID=0 in order to have delta-syncrepl working? Does the following query confirm the lack of the contextCSN value for SID=0? ldapsearch -ZZ -h ldap.example.org -LLL -x -s base -b dc=example,dc=org contextCSN dn: dc=example,dc=org contextCSN: 20140925113354.230424Z#000000#001#000000 contextCSN: 20140925113307.523494Z#000000#002#000000 If the mirror mode cluster is in production, do I have any hope to setup delta-syncrepl? Thank you, Francesco

slapo-refint not working on consumer.
by Mike Hulsman 25 Sep '14

25 Sep '14

Hi, When testing slapo-refint functionality in a configuration with mirror node masters, and a Delta-syncrepl consumer. I see that refint is working between the 2 providers, but not on the consumer. Using Openldap 2.4.39 on all instances. Database is hdb After renaming a uid the ContextCSN on all instances are the same, so changes are propagated successful. Every change if replicated properly, except for refint on a consumer. The refint configuration: overlay refint refint_attributes uniqueMember refint_nothing cn=Manager,o=test The logfile on the consumer: Sep 23 17:05:12 sldapa01 slapd[1727]: do_syncrep2: rid=101

way to validate server certificate
by Bin Lu 24 Sep '14

24 Sep '14

Hi, Does openldap provide APIs to do server certificate validation? Can I retrieve the server cert from LDAP connection and do the validation myself or by passing the trusted CA list openldap will do it (in this case, how the hostname matching with the subject DN is performed)? Thanks a lot in advance, -blu

Delta-syncrepl Consumer refresh entry
by unimore 24 Sep '14

24 Sep '14

Hi all, once in a while, a modification entry in cn=accesslog on provider is lost by consumer (both openldap-2.4.39). Later modifies on the same entry are cought up, but entry is now inconsistent. If I am right, eventually a "janitor process" recognizes messed up entries and fixes them, but in my limited scenario it could take hours. Is there a way to force consumer to refresh a given entry? Thank you for your patience, Francesco

unique overlay on a per branch basis

Assuming branches like: ou=people,ou=company1,dc=example,dc=com ou=people,ou=company2,dc=example,dc=com Is it possible to use a regular expression in the configuration to ensure a unique uid attribute in each branch but allow an identical uid attribute in different companies like: uid=Bob,ou=people,ou=company1,dc=example,dc=com uid=Bob,ou=people,ou=company2,dc=example,dc=com I ask because the man page for slapo-unique seems to suggest only absolute dn's Craig White System Administrator O 623-201-8179 M 602-377-9752 [cid:image001.png@01CF86FE.42D51630] SkyTouch Technology 4225 E.

troubles while setting-up ldap server + pam
by Ivaylo Ganchev 24 Sep '14

24 Sep '14

Hello, I am installing openldap in my cathedra and am running into a strange problem. Currently I configured the server and imported some entries (from the existing nis base). Then I set-up a client station. Unfortunately I am currently unable to log-in with a user account on the client station. The strange problem consists in the following : - When I use libnss_ldap and libpam_ldap the client sends multiple requests, receives multiple answers (with correct values for the given user), but then at one moment the server sends a FIN,ACK packet and in the auth.log of the client machine I see a message saying "failed to bind to ldap server" or something like this. I get this information from a network analyzer. From the server side everything seems OK. - When I use libnss_ldapd and libpam_ldapd, the communication is OK, but it seems that the client is not asking for the userPassword agrument and so, there is no way to login (it only asks for "loginShell cn gidNumber uidNumber objectClass homeDirectory gecos uid" and then in another request "shadowExpire shadowInactive shadowFlag shadowWarning shadowLastChange uid shadowMin shadowMax" I am able to make a ldapsearch from the client side with the binddn specified in the pam_ldap.conf and libnss_ldap.conf and all the information is successfully retrieved. Any advices are welcomed. Thanks, -- Ivaylo
