group email addresses
by Brendan Kearney 22 Jun '15

22 Jun '15

i have done some reading, and it seems that no official standard exists for group email addresses. to that end, i am looking to enlighten myself about what is done to provide mail addresses for groupOfNames groups. i would imagine there is some overlap between what many or most folks do and that would be a good starting point for me. i figure its something like "you have 7 steps to perform, and everyone does step 1,2,3 and 5 the same way. the rest, you are on your own for." i want to setup mailboxes for these groups, for example: cn=ldapAdmins,ou=domainGroups,ou=Groups,dc=bpk2,dc=com cn=ldapEngineers,ou=domainGroups,ou=Groups,dc=bpk2,dc=com these are groupOfNames structural groups, with top and posixGroup classes as aux. where do most folks begin, when setting up group mailboxes? i found a schema that is not official and has been extended with the same names but different numerical OIDs. I am not sure if this is the right path to follow, or if something more "standards focused" is appropriate. any help is appreciated. thanks, brendan

does slapd store/cache TLS certs
by lejeczek 18 Jun '15

18 Jun '15

hi everybody, I could not connect to slapd, command would fail with infamous: TLS: error: connect - force handshake failure: errno 0 - moznss error -5938 TLS: can't connect: TLS error -5938:Encountered end of file. ldap_err2string ldap_start_tls: Connect error (-11) additional info: TLS error -5938:Encountered end of file I was positive about certs, restarted daemons, looked at other obvious places, etc. - nothing. Only after I removed database & config files, recreated/restarted the whole slap it worded. Would it be that slapd caches certificates somewhere and does not re-read those upon restart? many thanks

Hi, I have a problem with meta backend feature. I need to get data from two different LDAP under a unique dn. The two ldap are an active directory and another ldap that should be on the same Open LDAP instance of the meta backend. Actually to test the solution I'm usind Open LDAP Windows version.

proxy to AD does not work during login client machine
by Leo Xiao 17 Jun '15

17 Jun '15

Hi technical, I hit a problem during configure proxy to AD. I can run command: $ldapsearch -x -h localhost -LLL -b dc=mydomain,dc=local -D cn=open,cn=users,dc=mydomain,dc=local -W "(cn=open1)" cn sAMAccountName which return the SAMACCOUNTNAME:open successfully. --- This may mean the proxy works well. But if I run command with out -D -D cn=open,cn=users,dc=mydomain,dc=local. The search will failed. when I try to login my client machine with AD user. It always failed. --- I can login with openldapuser successfully. I think I need some configuration to force the -D in slapd.con. Is there any problems with my slapd.conf? Or any trouble shooting comments? Appreciate it very much. Below is my slapd.conf: ####################################################################### # database definitions ####################################################################### database ldap suffix "DC=mydomain,DC=local" uri ldap://dc-ad.mydomain.local/ chase-referrals no rebind-as-user yes idassert-bind bindmethod=simple binddn="CN=open,OU=users,DC=mydomain,DC=local" credentials=open mode=none flags=non-prescriptive idassert-authzFrom "*" Thanks, Leo

problem using redundant ldap servers with keystone
by Chris Card 15 Jun '15

15 Jun '15

Hi, I have an HA OpenStack installation with a keystone domain backed by an LDAP server. I want to make the installation resilient in the case of an LDAP server failure, so I have configured keystone with a space-separated list of LDAP server urls in the [ldap] url option. This configuration appears to work well if I e.g. stop slapd on one of the LDAP servers - I can login to horizon as a user from the LDAP directory as long as one of the LDAP servers is running slapd. But if I shutdown one of the LDAP servers, login to horizon fails and the browser (chrome in this case) says "No data received". I've turned on debug logging in keystone, and as far as I can see the LDAP requests are still working; indeed cli commands like "openstack user list --domain <domain>" which get data from LDAP still work. Any ideas? [openstack juno, centos 7, keystone and horizon running as wsgi apps under Apache] Chris

The first one got through fine, which you could easily verify by looking at the list archives. b) Not enough information provided here to go on. Are all server IDs unique? Are all syncrepl clauses unique per DB? Personally I've never found ntpd particularly good at keeping clocks in sync. I've generally resorted to running ntpdate frequently out of cron, particularly for VMs. --Quanah -- Quanah Gibson-Mount Platform Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration
