Trouble with nisnetgrouptriple syntax / RFC 2307
by Jeff Blaine 16 Jul '08

16 Jul '08

I've come across the same problem as the original poster found here: http://www.openldap.org/lists/openldap-technical/200804/msg00127.html The only reply to him indicated that his syntax was incorrect for nisnetgrouptriple according to RFC 2307. I cannot see how it is invalid based on the syntax definition from RFC 2307. My example: > dn: cn=users1,ou=Netgroup,dc=rcf,dc=foo,dc=com > objectClass: nisNetgroup > objectClass: top > cn: users1 > nisNetgroupTriple: (-,asgen2m,) > nisNetgroupTriple: (-,apdons,) > nisNetgroupTriple: (-,ffeins,) > nisNetgroupTriple: (-,faullton,) The syntax definition: > nisnetgrouptriple = "(" hostname "," username "," domainname ")" > hostname = "" / "-" / keystring > username = "" / "-" / keystring > domainname = "" / "-" / keystring Does that not state that hostname, username, domainname can each be ANY of: empty - keystring ?? Any guidance would be welcome! Jeff Blaine

N-way multimaster
by Miguel Jinez 16 Jul '08

16 Jul '08

Hi. I need help to fix a problem. I am running openLdap 2.4 I have configurated 2 multimaster servers, which works fine, but I was thinking what happen if one of them die? When that master is restarted read the "logold" parameter in the other master and synchronize the changes, problem solved. But what happen if one master dies, meanwhile the other master performs changes in the Ldap tree (add, modify, delete) and that master dies too? I have test it and the changes that I made in the second master are not synchronized on the first one, and I don t know how I can synchronize the changes, I have accesslog configurated, I can see in the second one log these changes but the first one doesn t read it when is restarted. I need your help. sorry by the bad english. Migue

slapd was refusing connections from local clients
by Haim [Howard] Roman 15 Jul '08

15 Jul '08

I had a strange situation where the slapd would accept connections from other machines, but not from the local host. It didn't matter whether the local client program was the RADIUS server or ldapsearch. According to netstat & lsof, slapd was listening on all interfaces. Setup: * CentOS release 4.6 * slapd 2.2.13 (Jul 11 2008 09:16:05) (CentOS package) * This slapd maintains a replica data base. (The slapd on the master server is slapd 2.3.35, Jun 11 2007, running on Solaris 10.) * FreeRADIUS Version 1.0.1, built on May 10 2007 -- it uses the local slapd to get user names & passwords. Yesterday we had a power outage, and the UPS didn't work :-( Someone suggested that maybe things came up in the wrong order & that a reboot would help. And the reboot did indeed solve the problem. But I'd still like to know what happened. Before the reboot, I even tried turning on the following log levels (in /etc/slapd.conf): loglevel conns config stats sync packets BER ACL none But I really couldn't find any messages that helped me understand *why* I had this strange problem. Any suggestions, or even pointers on how to find out? Thanks. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Haim (Howard) Roman Computer Center, Jerusalem College of Technology roman(a)jct.ac.il Phone: 052-8-592-599 (6022 from within Machon Lev)

Newbie OpenLDAP woes
by Kristen Walker 11 Jul '08

11 Jul '08

Hi everyone, I am new to OpenLDAP and this list. I joined because I am trying to set up an OpenLDAP server so that Moodle and ELGG can authenticate users from the LDAP server. It is a little more difficult than I thought it would be, and I am running into some frustrating problems that I don't understand. I am hoping someone here might be able to help. I am using Ubuntu and using the book Mastering OpenLDAP as my guide. I have the server set up, edited config files and installed phpldapadmin to make things a little easier for me. I added my first entries but do not see them when I do a search, and nothing appears under my base in phpldapadmin (see attached screen shot). I don't get any complaints when I add the entries from my .ldif file, so I just don't understand why they don't seem to end up in my directory. If I do this command, sudo slapcat -a '(uid=barbara)' , the result is: dn: ou: Users uid: barbara sn: Jensen cn: Barbara Jensen givenName: Barbara displayName: Barbara Jensen mail: barbara(a)example.com userPassword:: c2VjcmV0 objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson structuralObjectClass: inetOrgPerson entryUUID: 8565f97e-e25b-102c-828c-238ab0ab2691 creatorsName: cn=Manager,dc=example,dc=com modifiersName: cn=Manager,dc=example,dc=com createTimestamp: 20080709233555Z modifyTimestamp: 20080709233555Z entryCSN: 20080709233555Z#000005#00#000000 So, it seems like there is a user with uid barbara in the directory. But if I try using ldapsearch to find that user, and I use this command, ldapsearch -x -D 'cn=Manager,dc=example,dc=com' -b 'ou=Users,dc=example,dc=com' -LLL '(userID=barbara)' + I get this: No such object (32) Also, it seems like I can't connect to my database unless I do an anonymous bind. When I try typing in a password to login to phpldapadmin it rejects my credentials and the same thing when I try using -w with a password on the command line. Thanks so much for any and all help in advance! -Kristen -- Kristen Walker Digital Media Resources Developer Instructional Media Services Santa Barbara County Education Office 4400 Cathedral Oaks Road P.O.

Problems using OpenLPAP for authentification of users: Client library issues STARTTLS but TLS is not configured
by Jörg Spilker 10 Jul '08

10 Jul '08

Hi, well, i don´t know what i´m doing wrong. I just want to authenticate unix and windows users against OpenLDAP Database. I followed some howtos to setup openldap, winbind etc. and nearly everything seems just fine. But authenticating unix users finally doesn´t work. I´ve attached the syslog output. START TLS extension not supportet. This is true, as i haven´t configured OpenLPAP for TLS. But my LDAP client configuration doesn´t specify an LDAPS URL. So what´s going wrong?

LDAP binding failure to Active Directory using certificates
by Clayton Tucker 10 Jul '08

10 Jul '08

Greetings: I'm wondering if anyone has had any experience with this problem. I am endevouring to use ldapmodify (from OpenLDAP 2.3) to connect to a domain controller (named intacta) in our Active Directory forest and perform account management operations. For this purpose, the bind to the AD's LDAP must provide credentials of a user with the rights to manage accounts in the domain in question. I'm attempting to perform the authentication using certificates generated by a certificate authority which we have established on a domain controller in the forest root domain of our AD (not the same domain as the domain where we are trying to perform account management but is the same forest). The bind account is named test_account_manager and the user certificate CSCFForestAccount.cer (listed below) is name mapped to the account. All domain controllers in the forest have domain controller certificates distributed to them from the forest's certificate authority. Below is the content of my .ldaprc file on the Solaris 8 host where I'm attempting to run ldapmodify. As stated above, the TLS_CERT certificate is name mapped to the test_account_manager account in the AD. The account of coarse, has a password but the key file has no access password as I believe is necessary for the current version of openldap. TLS_CACERT /u/ctucker/LDAP_Cert/CSCFTrustedCA.pem.cer TLS_CERT /u/ctucker/LDAP_Cert/CSCFForestAccount.cer TLS_KEY /u/ctucker/LDAP_Cert/private_test1.pem TLS_REQCERT demand Below is the output of an ldapmodify command run on the Solaris 8 host. When this command is run entries confirming the logon of the test_account_manager account appear in the security event logs of the domain controller intacta as a successful logon. This suggests that the connection was properly authenticated by the certificates for the user test_account_manager. However, the subsequent binding to LDAP fails with the error "Authentication method not supported" Any help with this persistent problem would be greatly appriciated. Thanks.

problem with openldap ssl client
by Sambuddho Chakravarty 10 Jul '08

10 Jul '08

Hello I have an openldap server running slapd on 636 (LDAPS) . When I connect from a ldap browser , I am able to successfully browse the database. However when I try to connect from a linux client machine (Ubuntu Server 8.04) I am not able to connect to the ldaps. However regular ldap works fine. The /etc/ldap.conf looks like this ssl start_tls ssl on tls_checkpeer tes tls_cacertdir /etc/ldap/cacerts tls_cacertfile /etc/ldap/cacert/cacert.pem #server IP uri ldaps://30.0.0.2/ pam_password md5 base dc=example,dc=com The /etc/ldap/ldap.conf file is like this URI ldaps://30.0.0.2/ TLS_CACERTDIR /etc/ldap/cacerts TLS_CACERT /etc/ldap/cacerts/cacert.pem HOST 30.0.0.2 BASE dc=example,dc=com The same configuration (with approprirate changes - replacing ldaps with ldap and so on) works fine for regular ldap. But the problem is the ldaps. When ldaps client is enabled and I do a getent passed , the /var/log/auth.log looks like this Jul 7 23:57:46 host3 getent: nss_ldap: reconnecting to LDAP server... Jul 7 23:57:46 host3 getent: nss_ldap: reconnecting to LDAP server (sleeping 1 seconds)... Jul 7 23:57:47 host3 getent: nss_ldap: could not search LDAP server - Server is unavailable Jul 7 23:58:18 host3 getent: nss_ldap: reconnecting to LDAP server... Please suggest where I could have gone wrong. Any suggestions would be really appreciated. Thanks Sambuddho
