auto incrementing digit pool
by mike＠grounded.net 28 Jan '11

28 Jan '11

Is there a way of creating an attribute which can be assigned a value which auto increments using an external file. In other words, say I use the employeeNumber attribute but I want the value to be entered by picking the next value from a file. In my file, I might have 000123 000124 000125 000126 000127 Then when I run an ldap connection from my remote application, it would pick the next number if it doesn't exist on any account. The next problem is I don't know how ldap works in terms of keeping track of things. When I sync my application database with ldap, does it, or can it, check all of the users to see if a value is assigned or is that beyond it's functions? Or, would keeping track of the values be something which needs to be done on the application side? The programmers tell me that there is no means of going back to ldap to identify if a user has been assigned a value, therefore, assign the next.

Failover Failure Advice
by Anton Chu 28 Jan '11

28 Jan '11

I've setup a master and slave ldap service for failover; however, I'd like some advice on how to keep the ldap clients cached with the ldap creds if ever the master and slave ldap server goes. I've tried to extend the time of the caching on nscd - name server caching daemon - but it doesnt work when I add ldap users to certain groups. I've also tried pam caching credentials but doesn't work that well either. Finally, I also tried sssd but couldn't get it to work on my Ubuntu 10.10 clients. Anyone have simple solution that works when slave and master ldap servers get out of commission? I've thought about getent passwd >> /etc/passwd cron job, etc.

Setting OPENLDAP_FD_SETSIZE on an existing directory
by George Siddiqui 28 Jan '11

28 Jan '11

Hi, I recieved my first of these errrors from openldap server today. slapd[1648]: warning: cannot open /etc/hosts.deny: Too many open files The faqomatic suggest that I do the following: env CPPFLAGS="-DOPENLDAP_FD_ SETSIZE=8192" ./configure http://www.openldap.org/faq/data/cache/1126.html Is there anyway I can set this without having to build openldap again?

by Raphael Ordinas 28 Jan '11

28 Jan '11

Hi everyone, I'm trying to setup a translucent proxy which is populating his local database as a syncrepl consumer. It works fine, changes on the master are replicated to the translucent, but i get an error in logs. Here is the extract from logs : bdb_modify: updated id=0000010d dn="uid=testuser,ou=people,dc=domain,dc=local" send_ldap_result: conn=-1 op=0 p=0 send_ldap_result: err=0 matched="" text="" syncrepl_entry: rid=002 be_modify uid=testuser,ou=people,dc=domain,dc=local (0) slap_queue_csn: queing 0x801de5670 20110127172543.325840Z#000000#000#000000 ==> translucent_modify: dc=domain,dc=local send_ldap_result: conn=-1 op=0 p=0 send_ldap_result: err=32 matched="" text="attempt to modify nonexistent local record" syncrepl_updateCookie: rid=002 be_modify failed (32) How can i solve this ?

Thanks. Made a note about the config directory. I've focused on following the FHS: http://www.pathname.com/fhs/ As it is a symlink it should be possible to put the config directory wherever you want (I guess that's what you did). How about replication verification? Can you confirm that its working?

slapo-cache and searches by dynlist (with !)
by Angel L. Mateo 27 Jan '11

27 Jan '11

Hello, I'm trying to use pcache overlay to cache queries done by dynlist overlay. This is the configuration I have: database hdb suffix <userSuffix> ... overylay dynlist dynlist-attrset labeledURIObject labeledURI # This is because, data obtained by dynlist is in another ldap directory database ldap suffix dc=mydomain,dc=com access ... uri ldap:/<anotherldap> ... overlay pcache pcache hdb 1000 1 10 60 pcacheAttrset 0 irisClassifCode sn1 givenName pcacheMaxQueries 10000 pcacheTemplate (&(objectClass=)(irisPersonalUniqueId=)) 0 3600 directory /var/lib/ldap/cachepublica cachesize 100 The pcacheTemplate is because labeledURI attributes are in the form: labeledURI: ldap:///dc=mydomain,dc=com?irisClassifCode,sn1,givenName?one? (irisPersonalUniqueID=<someCode>) The final search done in the final ldap directory is: filter="(&(!(objectClass=labeledURIObject))(irisPersonalUniqueID=<someCode>))" so I think I need to negate the search in the pcacheTemplate, but I can't because I get the error: /etc/ldap/slapd.conf: line 419: unable to parse template: AttributeDescription contains inappropriate characters. whenever I try to put the '!' in the template. Is there any way to cache this kind of query? -- Angel L.

MemberOf attribute not being returned
by Mark Cairney 27 Jan '11

Hi, I'm sure this was working in the past on this server but Im now not getting anything returned when I request the memberOf attribute. I compiled OpenLDAP 2.4.23 with the following flags: ./configure --prefix=/usr/local/authz --enable-meta --enable-ldap --enable-bdb --enable-monitor --enable-syncprov --enable-translucent --enable-memberof --enable-dyngroup --enable-dynlist --with-threads --with-tls --with-cyrus-sasl --enable-syslog --enable-spasswd cd make depend make make test make install I'm using slapd.d and I have the following in /usr/local/authz/etc/openldap/slapd.d/cn=config/olcDatabase={1}bdb olcOverlay={0}dynlist.ldif olcOverlay={1}memberof.ldif olcOverlay={2}syncprov.ldif The contents of olcOverlay\=\{1\}memberof.ldif are: dn: olcOverlay={1}memberof objectClass: olcOverlayConfig objectClass: olcMemberOf olcMemberOfDangling: ignore olcMemberOfRefInt: FALSE olcMemberOfGroupOC: posixGroup olcMemberOfMemberAD: member olcMemberOfMemberOfAD: memberOf structuralObjectClass: olcMemberOf entryUUID: 4d5a3aa8-fbac-45c9-b259-941d13e02724 creatorsName: cn=config createTimestamp: 20100318151149Z entryCSN: 20100318151149.488341Z#000000#003#000000 modifiersName: cn=config modifyTimestamp: 20100318151149Z olcOverlay: {1}memberof The log is attached. -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

RE: MemberOf attribute not being returned
by Mark Cairney 27 Jan '11

27 Jan '11

Nevermind, I think I know what's happening. My user account was updated on our current live server running OpenLDAP 2.3 which doesn't have the MemberOf overlay. When this change was applied using syncrepl the memberOf field must have been removed. I'll take the old server out of the syncrepl but in the meantime is there any way to ensure this field is preserved when provisioning accounts in LDAP?

openldap memberof attribute
by Vincent Li 27 Jan '11

27 Jan '11

Hi, I am doing remote authentication using OpenLDAP to login BIGIP, BIGIP has a feature called remoterole to search attribute 'memberof' from LDAP server and once found the attribute, assign the remote user a role defined in various groups like admin, operator... the feature works for Active Directory, but I am unable to make it work for OpenLDAP, I couldn't find 'memberof' attribute in OpenLDAP schema, so I created the 'memberof' attribute in core.schema as below: [root@centos-vli schema]# diff -u core.schema core.schema.orig --- core.schema 2011-01-24 23:54:42.000000000 -0800 +++ core.schema.orig 2011-01-24 23:46:11.000000000 -0800 @@ -345,10 +345,6 @@ DESC 'X.520(4th): pseudonym for the object' SUP name ) -attributetype ( 2.5.4.66 NAME 'memberof' - DESC 'RFC2256: member of a group' - SUP distinguishedName ) - # Standard object classes from RFC2256 # system schema @@ -425,7 +421,7 @@ objectclass ( 2.5.6.9 NAME 'groupOfNames' DESC 'RFC2256: a group of names (DNs)' SUP top STRUCTURAL - MUST ( member $ memberof $ cn ) + MUST ( member $ cn ) MAY ( businessCategory $ seeAlso $ owner $ ou $ o $ description ) ) objectclass ( 2.5.6.10 NAME 'residentialPerson' and here is my sample ldif file: dn: ou=groups,dc=example,dc=com objectclass:organizationalunit ou: groups description: generic groups branch # create the itpeople entry under groups dn: cn=administrator,ou=groups,dc=example,dc=com objectclass: groupofnames cn: administrator description: bigip admin group member: uid=user5,ou=people,dc=example,dc=com dn: uid=user5,ou=People,dc=example,dc=com uid: user5 cn: user5 objectClass: top objectClass: posixaccount objectClass: shadowaccount objectClass: groupOfNames userPassword: secret shadowLastChange: 14997 shadowMin: 0 shadowMax: 99999 shadowWarning: 7 loginShell: /bin/bash uidNumber: 505 gidNumber: 505 homeDirectory: /home/user5 member: cn=administrator,ou=groups,dc=example,dc=com memberof: cn=administrator,ou=groups,dc=example,dc=com I can login BIGIP fine with user5, but I can't get the administrator role defined in BIGIP, is it something I configured wrong in OpenLDAP or the problem is on BIGIP Thanks Vincent
