rwm-map like functionality that copies attributes
by Alexander 'Leo' Bergolth 05 Mar '10

05 Mar '10

Hi! I'd like to implement some kind of attribute-mapping so that the attributes cn and displayName contain the same values. I am thinking about something similar to rwm-map attribute displayName cn However, I don't want to map the attribute names but I want to copy the attribute values, so I guess rwm-map won't be the right way to do it. I found an old mail in the archives that suggests to write an own overlay for that job... http://www.mail-archive.com/openldap-software@openldap.org/msg12720.html I wonder if such kind of functionality has already been developed since that time? Thanks, --leo -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria

OpenLDAP authentication problem, need help
by Veikko "Wexi" Skurnik 05 Mar '10

05 Mar '10

Hi all, my OpenLDAP server was working fine, user authentication for workstations and the postfix/dovecot mail server worked as they should, I was about to configure gnarwl and now for some reason users cannot authenticate using the LDAP server. Dovecot also say that it cannot connect to the server (the mail server and OpenLDAP are running on the same machine). I can login to the LDAP server using phpLDAPadmin but i cannot find anything that would be the cause of the problem. The starnge thing is that I did not do any modifications to the OpenLDAP config files that could cause the problem (or at least i think so =)). I've been looking through the config files and made sure that OpenLDAP is running and now I'm running out of ideas. Any help would be greatly appreciated and I'll be more than happy to provide more info needed to solve this problem. Thanks in advance Veikko "Wexi" Skurnik -- * Veikko "Wexi" Skurnik: +358(44)5288338 * * wexi(a)wexin.net Wexi@IRCNet * * Näyttämönkatu 4 B 12 33720 Tampere * * "Kosminen balanssi ei saa järkkyä" *

SASL Auth with -d ok, otherwise internal error 80
by lists＠supported.de 05 Mar '10

05 Mar '10

Hello list, this is my first time trying to set up SASL, I'm probably doing something wrong. Anyhow: - I'm on OpenSolaris snv_127 - using SUNWopenldap from IPS (which links with bdb 4.7.25) I got strange slapd (and slapcat) hangs (probably in bdb). This forced me to set it all up from source. - I've compiled latest bdb 4.8 from source - I've compiled latest OpenLDAP 2.4.21 from source with this configure args: $ cat myconfigure export CFLAGS="-I/usr/local/BerkeleyDB.4.8/include" \ CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include" \ LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib \ -R/usr/local/BerkeleyDB.4.8/lib" ./configure -C \ --prefix=/usr/local/openldap \ --enable-spasswd \ --with-cyrus-sasl \ --enable-syslog - I've got my slapd.conf [1] in place and initialized my directory - simple bind always works - I want SASL with DIGEST-MD5 auth. - when starting slapd with -d XXX (-d 256) SASL auth. works !! $ ldapsearch -v -h localhost -p 10389 -LLL -U ldapadmin -D "cn=ldapadmin,ou=Users,dc=hh,dc=supported,dc=de" -b "ou=Users,dc=hh,dc=supported,dc=de" -s sub "cn=ldapadmin" '*' ldap_initialize( ldap://localhost:10389 ) SASL/DIGEST-MD5 authentication started Please enter your password: SASL username: ldapadmin SASL SSF: 128 SASL installing layers filter: cn=ldapadmin requesting: * dn: cn=ldapadmin,ou=Users,dc=hh,dc=supported,dc=de cn: ldapadmin gidNumber: 5000 objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: posixAccount objectClass: person objectClass: top sn: Admin uid: ldapadmin uidNumber: 5000 homeDirectory: /tmp userPassword:: ******** - when starting slapd without -d I get: $ ldapsearch -v -h localhost -LLL -U ldapadmin -D "cn=ldapadmin,ou=Users,dc=hh,dc=supported,dc=de" -b "ou=Users,dc=hh,dc=supported,dc=de" -s sub "cn=ldapadmin" ldap_initialize( ldap://localhost:10389 ) SASL/DIGEST-MD5 authentication started Please enter your password: ldap_sasl_interactive_bind_s: Internal (implementation specific) error (80) additional info: SASL(-1): generic failure: There's an additional problem in that slapd is not logging to syslogd.

OpenLdap mirrormode cluster with 2 slaves.
by Jan Hugo Prins 04 Mar '10

04 Mar '10

Hello, I have the following setup that gives me some issues at the moment. I have 2 servers running Fedora 10 with OpenLDAP 2.4.19 that are running in Mirrormode. The sync between those 2 servers works just fine. Besides that we have 2 frontend servers that rely heavily on ldap for mail delivery and mail transfers. To make this workable we thought about creating a readonly replica on these servers and tell the sendmail to use the local ldap as primary. When we had an old version on these servers (I think 2.4.12) everything worked fine. We now upgraded all servers to 2.4.19 and the configuration moved to slapd.d format, and now it looks like those 2 servers don't see the updates on the mirrormode backend anymore. I have to following config's, this was from before the migration to slapd.d: ================== master 1 ================== overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 serverID 3 # # Configure a replication consumer # syncrepl rid=1 provider=ldap://server2:389 type=refreshAndPersist retry="60 10 300 +" interval=00:00:05:00 searchbase="dc=domain,dc=com" filter="(objectClass=*)" attrs="*" scope=sub schemachecking=off bindmethod=simple binddn="cn=syncrepl,dc=domain,dc=com" credentials=password mirrormode on ================== master 2 ================== overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 serverID 4 # # Configure a replication consumer # syncrepl rid=1 provider=ldap://server1:389 type=refreshAndPersist retry="60 10 300 +" interval=00:00:05:00 searchbase="dc=domain,dc=com" filter="(objectClass=*)" attrs="*" scope=sub schemachecking=off bindmethod=simple binddn="cn=syncrepl,dc=domain,dc=com" credentials=password mirrormode on =================== slaves =================== overlay syncprov syncprov-checkpoint 100 10 # # Configure a replication consumer # syncrepl rid=1 provider=ldap://ldap:389 type=refreshOnly retry="60 1 120 1" interval=00:00:05:00 searchbase="dc=domain,dc=com" filter="(objectClass=*)" attrs="*" scope=sub schemachecking=off bindmethod=simple binddn="cn=syncrepl,dc=domain,dc=com" credentials=password updateref ldap://ldap.svc.be.nl:389 updateref ldap://ldap.lan.domain.com:389 ============================================ When I empty the DIT on a slave and start it again it gets the full DIT just fine and I checked this. But after that it is not updated anymore. Does anyone see here some obvious things I'm missing in these slave or master configs? Thanks a lot, Jan Hugo Prins

combine/link entries in different ou' s
by Marc Mertes 03 Mar '10

03 Mar '10

Hi everybody, I'm not a real pro in ldap yet, so I have a question about ou' s. I have here the main ou=people, where all users are in. Now I want to create a 2nd ou=radar. The goal is that I have a 2nd ou with just a few users, for authentication on some special servers. I want to have that seperated. My question is, if I can link or combine some users from ou=people to ou=radar, that I don't have to create the user a 2nd time? regards marc

back-sql/BDB question
by beniwtv＠relamp.tk 02 Mar '10

02 Mar '10

Hello, I have an OpenLDAP server configured with back-sql. The reason for this is that I need to export two simple tables as LDAP for contacts (groups and users) and I don't want a cron job syncing the two every x hours/minutes (ideally it should be instant). And also (ideally), if the two programs access the same database there are no inconsistencies between the two. All is working perfectly fine, except that changes to existing rows in the SQL database (MySQL) are not picked up until OpenLDAP is restarted. Adding new rows works fine, however. I guess that for each record in ldap_entries, OpenLDAP fetches the values on startup, but does not check them again, unless there is a new one which it has no data for. Am I correct here? Now, I'm wondering if anyone has experienced the same problem, and if there is a solution? Is this intentional? (could be) I'm too considering dropping back_sql and just modify the web application to also modify OpenLDAP directly via queries, however, I fear that if one of them goes down, data inconsistency might occur. (could be resolved with a cron script?) Any ideas? Thanks, Benedikt

Nssov Authorization without Authentication
by Chris Breneman 01 Mar '10

01 Mar '10

Is there a way to use nssov PAM LDAP for authorization (the PAM "account"), without using it for authentication? In my setup, I'm authenticating users with pam_krb5 separately, and I just want to use LDAP for authorization and nss. I got nssov working fine with nss, but not authorization. I want to use the authorizedService attribute of the user entry for authorization. My nssov configuration is: dn: olcOverlay={0}nssov,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig objectClass: olcNssOvConfig olcOverlay: {0}nssov olcNssSsd: passwd ldap:///ou=people,dc=cluenet,dc=org??one olcNssPam: userservice olcNssPamMinUid: 25000 After adding the required entry to the PAM configuration (the account section only), logins stop working - SSH just disconnects immediately after the password is entered. I suspect this is because I'm not using nssov for the PAM authentication. At the beginning of pam_authz() in nssov, I saw: /* We don't do authorization if they weren't authenticated by us */ if (BER_BVISEMPTY(&dn)) { rc = NSLCD_PAM_USER_UNKNOWN; goto finish; } Which leads me to believe that this is what is causing the problem. Indeed, when I change NSLCD_PAM_USER_UNKNOWN to NSLCD_PAM_SUCCESS there, logins succeed (but authorization is not performed). If I just comment out that block, logins still don't work, but I get the "service not permitted" message. Is there some way to make authorization work without first performing authentication through nssov? Thanks, Chris Breneman

Re: Check password module/ppolicy problem on Solaris 10 (2.4.21 OL sources)

Hello, Wow. I feel like an idiot. I solved my problem. My OpenSUSE clients were sending passwords as md5 and cause my openldap server not able to read the password information. I changed the clients to send password as "exop" and that did the trick. Jose --- On Thu, 2/25/10, Jose G. Torres <jogeedaklown(a)yahoo.com> wrote: > From: Jose G.
