LDAP Entry with gecos
by rodrigo tavares 09 Aug '12

09 Aug '12

Hello ! I create one samba user with command: smbldap-useradd -a xbox -c "Game XBOX" -S "Sell games" -d /home/xbox -s /bin/false Then I type: smbldap-passwd xbox #define password ldap user smbpasswd -a xbox # create user samba So. I can to make login in my domain. I checked atributtes gecos is: SystemUser. After I log in domain, in the top menu windows show:System User. I changed this value gecos, but each login the gecos show System User. It´s no changed never. This command in line 2, not define gecos in LDAP, give default with "System user". If i change the value gecos in LDAP before te fist login, the gecos is with value correct. Any sugesstion ? Thanks. Rodrigo Faria

Dear fellows, i am planning to build a mail server and would like to use the following technologies : OpenBSD 5.1 amd64 qmail-ldap-1.03-20120221 qmail-1.03 Does anybody here run an environment like ? Are you aware of buggy stuf like openldap eating all system memory while qmail connect/disconnect to it (slapd) ? Is there any problem with the latest ldap patch release to be applied to stock qmail-1.03 ? Thanks a lot for your time and cooperation. []s gustavo. PS: Anyone from Brazil in this mailing list ?

got into a "checksum error" situation
by Jeff Dickens 08 Aug '12

08 Aug '12

I was following an Ubuntu howto at https://help.ubuntu.com/12.04/serverguide/openldap-server.html ,which has served me well so far, and I was working on the part where TLS is set up. I made an ldif file like: dn: cn=config add: olcTLSCACertificateFile olcTLSCACertificateFile: /etc/ssl/certs/cacert.pem - add: olcTLSCertificateFile olcTLSCertificateFile: /etc/ssl/certs/grackle_slapd_cert.pem - add: olcTLSCertificateKeyFile olcTLSCertificateKeyFile: /etc/ssl/private/grackle_slapd_key.pem and, well, I blew it.. I initially had a typo in it, and the server cert and key weren't where I said they were. I ran ldapmodify to load the ldif file above: ldapmodify -Y EXTERNAL -H ldapi:/// -f /etc/ssl/certinfo.ldif Then I tried to restart slapd, and perhaps unsurprisingly it did not restart. Aug 8 16:41:30 grackle slapd[1660]: @(#) $OpenLDAP: slapd (Jul 26 2012 00:10:41) $#012#011buildd@aatxe :/build/buildd/openldap-2.4.28/debian/build/servers/slapd Aug 8 16:41:30 grackle slapd[1660]: main: TLS init def ctx failed: -1 Aug 8 16:41:30 grackle slapd[1660]: slapd stopped. Aug 8 16:41:30 grackle slapd[1660]: connections_destroy: nothing to destroy. So I thought I just fix my ldif file, which I did, and then run ldapmodify again. But no, that clearly wasn't going to work because slapd wasn't running. Not knowing what else to do, I removed the lines containing "olcTLS" from /etc/ldap/slapd.d/cn=config.ldif. Then I was able to restart slapd (congratulating myself) and then re-ran my ldapmodify command to enter the correct locations of the cert and key. But I still get a checksum error in syslog: Aug 8 17:04:53 grackle slapd[2028]: slapd starting Aug 8 17:05:01 grackle slapd[2028]: ldif_read_file: checksum error on "/etc/ldap /slapd.d/cn=config.ldif" I haven't even tried to see if I have TLS working, but I have two questions: #1. How should I have recovered from this (human) error? What I did didn't seem to work out very well. and #2. How do I un-screw my config and resolve the checksum problem? Thanks in advance for any assistance. -- * Jeff Dickens* IT Manager 978-632-1513

Virtual view using slapd-relay: dn mapping failure
by Guillaume Rousse 08 Aug '12

08 Aug '12

Hello list. I'm trying to provide a virtual view of the user branch in my legacy ldap directory. Basically, the real branch uses 'localLogin' as login attribute, and not 'uid', as usual, which unfortunatly breaks hard-coded rules in some applications. This configuration creates a virtual 'ou=users' branch, mapped on actual 'ou=people', with real 'localLogin' attribute mapped to 'uid', and real 'uid' one removed: # virtual database database relay suffix ou=users,dc=domain relay ou=people,dc=domain overlay rwm rwm-suffixmassage ou=people,dc=domain rwm-map attribute uid localLogin rwm-map attribute uid access to dn.subtree="ou=users,dc=domain" attrs=userPassword by anonymous auth access to dn.subtree="ou=users,dc=domain" by * read # main database database bdb suffix "dc=domain" However, the actual 'uid' attribute is also used as RDN in the actual branch, and bind operation fails, because DN mapping is incomplete: uid=rousse,ou=users,dc=domain -> uid=rousse,ou=people,dc=domain Wheras I'd need this, where somethingelse is the value for the actual 'uid' attribute: uid=rousse,ou=users,dc=domain -> uid=somethingelse,ou=people,dc=domain I read rwm man page carefully, but it is a bit tough to understand. So, how am I supposed to achieve this ? -- BOFH excuse #219: Recursivity. Call back if it happens again.

sasl bind error -1 because of socket error 54
by Max Kunz 07 Aug '12

07 Aug '12

Hello, i try to bind to an server using the ldap_sals_bind_s function. The Host is not localhost, but is accessible via internet. I'v tested the connection with a java based ldap browser. When i try to do this using my simple c++ program, it fails with error -1. Here is what the program actually do: //initialize returns success result = ldap_initialize( &ld, host); result = ldap_set_option( ld, LDAP_OPT_PROTOCOL_VERSION, LDAP_VERSION3); //set this option only after successful bind? result = ldap_set_option(ld, LDAP_OPT_X_TLS_REQUIRE_CERT, LDAP_OPT_X_TLS_NEVER); //the synchronous bind function returns -1 server down result = ldap_sasl_bind_s(ld, root_dn, LDAP_SASL_SIMPLE, &credential, NULL,NULL, &serverReturnedCredentials); When I use the asynchronous ldap_sals_bind() function, it returns 0 ldap_success. (I`m also able to create a simple socket to this particular server and port). The error -1 comes from the following ldap_result() function. The problem here is that the socket throws a sock_errno 54 (connection reset by peer). Someone an idea why the connection always will be disturbed? Thanks for any help best regards, Max

Referral to single attributes
by Florian Götz 07 Aug '12

07 Aug '12

Hi, maybe someone has experienced the same problem. Take the following example. You would like to use one LDAP server (replicated of course) for multiple Domains. Like ou=users,ou=department1,dc=company,dc=de ou=users,ou=department2,dc=company,dc=de ou=users,ou=maindep,dc=company,dc=de ... Each department has its own domain, all users are part of maindep, some of those users are part of dep1 too and some of dep2. So you have the maindep tree for the general use (uid and password for things like mail, vpn and a genereal purpose domain) and the smaller dep1 or dep2 for the use with the workstations of the department. The uid of a user is always the same across the trees (uid=mikecharlie,ou=dep1,... = uid=mikecharlie,ou=maindep). The single departments are responsible for their users (creation and deletion of accounts in their subtrees). The maindep-Tree gets managed by IT center staff. Now every department could work with their domain and users (and only those) , but all users would have a general "account" for stuff that doesnt belong to their department alone. The big problem is the sync of the passwords from subtree to subtree (dep1 to maindep or dep2 to maindep). Our users get confused if they have password1 for the login at a workstation and password2 for mail etc. But the departments want to have their own domains where they have the control who is able to login or not, BUT they want to have syncronized passwords. Is there a possibility to refer to single attributes? Like uid=mikecharlie,ou=dep1,dc=company,dc=de -> userPassword -> look at uid=mikecharlie,ou=maindep,dc=hs-mannheim,dc=de -> userPassword.

ACL processing: subtractive privs (using control continue)
by Dora Paula 06 Aug '12

06 Aug '12

Hi List, just another short question regarding incremental privileges, given the following acl: access to dn.subtree="o=test" attrs=description by self =dxcsraz continue by users -z by * none Subtracting "z" results in the access mask "=dxcsr". As I expected the resulting access mask to be "=dxcsra", I would like to know whether "=dxcsr" is the correct result, and if so, why? Many thanks again! A small testbed containing sample ldif data, ldapmodify test command and the produced slapd.log (level 128) follows here: sample ldif data: =============== dn: o=test objectClass: organization objectClass: top o: test dn: ou=persons,o=test objectClass: organizationalUnit objectClass: top ou: persons dn: cn=PersonA,ou=persons,o=test objectClass: person objectClass: top cn: PersonA sn: PersonA userPassword:: UGVyc29uQQ== test command using ldapmodify: ============================= deepee@test:~$ /opt/openldap-acl/bin/ldapmodify -x -H "ldap://localhost:1389" -D "cn=PersonA,ou=persons,o=test" -w PersonA <<EOF dn: cn=PersonA,ou=persons,o=test changetype: modify add: description description: PersonA1 EOF modifying entry "cn=PersonA,ou=persons,o=test" ldap_modify: Insufficient access (50) slapd.log level 128: ================= 501fb8b7 => access_allowed: result not in cache (userPassword) 501fb8b7 => access_allowed: auth access to "cn=PersonA,ou=persons,o=test" "userPassword" requested 501fb8b7 => dn: [1] o=test 501fb8b7 => acl_get: [1] matched 501fb8b7 => acl_get: [2] attr userPassword 501fb8b7 => acl_mask: access to entry "cn=PersonA,ou=persons,o=test", attr "userPassword" requested 501fb8b7 => acl_mask: to value by "", (=0) 501fb8b7 <= check a_dn_pat: self 501fb8b7 <= check a_dn_pat: users 501fb8b7 <= check a_dn_pat: anonymous 501fb8b7 <= acl_mask: [3] applying auth(=xd) (stop) 501fb8b7 <= acl_mask: [3] mask: auth(=xd) 501fb8b7 => slap_access_allowed: auth access granted by auth(=xd) 501fb8b7 => access_allowed: auth access granted by auth(=xd) 501fb8b7 => access_allowed: result not in cache (description) 501fb8b7 => access_allowed: add access to "cn=PersonA,ou=persons,o=test" "description" requested 501fb8b7 => dn: [1] o=test 501fb8b7 => acl_get: [1] matched 501fb8b7 => acl_get: [1] attr description 501fb8b7 => acl_mask: access to entry "cn=PersonA,ou=persons,o=test", attr "description" requested 501fb8b7 => acl_mask: to value by "cn=persona,ou=persons,o=test", (=0) 501fb8b7 <= check a_dn_pat: self 501fb8b7 <= acl_mask: [1] applying =wrscxd (continue) 501fb8b7 <= acl_mask: [1] mask: =wrscxd 501fb8b7 <= check a_dn_pat: users 501fb8b7 <= acl_mask: [2] applying -z (stop) 501fb8b7 <= acl_mask: [2] mask: =rscxd 501fb8b7 => slap_access_allowed: add access denied by =rscxd 501fb8b7 => access_allowed: no more rules BTW: Replacing the first by clause using "self write" or "self =dxcsrw", also results in "=dxcsr" JFF: Replacing the second by clause using "users -a", the test results in the above mask (=dxcsr), too.
