Duplicated username in Local users and LDAP
by Phillip 10 Nov '06

10 Nov '06

Hi all, I meet some trouble when there are duplicated username in both local users list and LDAP users list, and I think it may cause security problems, for example, in my case, "root" and "admin" account from LDAP could even control the whole system. I do not want this happens. Would you please give me some advices on how to dare with this duplicated username issue? Kind regards, Phillip

open ldap with SASL & GSSAPI
by Maxwell Bottiger 09 Nov '06

09 Nov '06

Hello all, I've found lots of information about problems related to mine in the FAQ and around the net, but I don't have a solution yet. Here's my setup: Open Ldap 2.2 MIT Kerberos SASL 2.1.20 I'm using ldap to provide directory services and user info to some linux workstations. This was working, but after upgrading a test machine to Fedora 6 I've started having some serious problems. [sleepylight@minitop ~]$ ldapsearch -H ldap://ns.jive-turkey.net -Y GSSAPI SASL/GSSAPI authentication started ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: SASL(-13): authentication failure: GSSAPI Failure: gss_accept_sec_context I figure this is one of three possible problems. 1 - saslauthd isn't working right 2 - ldap isn't talking to sasl correctly 3 - I've done something wrong with my ldap quires. Kerberos seems to work fine. I can get my credentials with kinit, and the GSSAPI credentials are working for ssh logins. Also, I can use testsaslauthd and get a success from the authd server. [sleepylight@ns ~]$ /usr/sbin/testsaslauthd -r JIVE-TURKEY.NET -s ldap -u sleepylight -p ********* 0: OK "Success." So I think my problem is #2 or #3. I'm not sure which, so if anyone has some feedback I'm happy to try it out. I'll include some possibly relevant material at the end of this email. Thanks for reading!

Speed of slapadd for BDB on a Linux machine
by Ralf Narozny 09 Nov '06

09 Nov '06

Hello, I'm trying to migrate about 19 million entries from OpenLDAP 2.0 to the new 2.3. Conversion and such things are done, but inserting the data takes days. I hope someone can point me to some helpful direction, because 22 Entries/sec is not too good, especially not for real life use... I'm using the following to insert the data slapadd -q -v -c My DB_CONFIG looks like this: set_cachesize 1 524288000 1 set_lg_regionmax 262144 set_lg_bsize 2097152 Our OpenLDAP version is 2.3.27.

Don't want to be prompted for the password
by Sadique Puthen 09 Nov '06

09 Nov '06

Hi, We are using SASL/DIGEST-MD5 for authentication to ldap database and don't want to be prompted for the password and need the password to be taken from a file. Can we specify it in /etc/ldap.conf globally or in .ldaprc individually? I expect it to work like SASL/GSSAPI when we run an ldapsearch after retrieving the ticket for the user. Is it possible? Regards, Sadique

DN syntax question
by Miek Gieben 09 Nov '06

09 Nov '06

Hello, I'm not sure this is the correct list, but here it goes. I'm creating a ldap tree with the usual layout: o=companyName,ou=relations,dc=xxx,dc=yy,dc=zz Where companyName is a customer. Adding entries with this DN works and I can query the tree, etc. etc. Now some customers can also have clients which should also be represented in this tree. This would lead to the following DN to be created: o=client,ou=Organizations,o=companyName,ou=relations,dc=xxx,dc=yy,dc=zz So: 'o=client,ou=Organizations' is placed below 'o=companyName'. Now when I try to add this to openldap I get this in the logs: slapd[3418]: connection_get(10) slapd[3418]: do_add: dn (o=client,ou=Organizations,o=companyName,ou=relations,dc=xxx,dc=yy,dc=zz) slapd[3418]: ==> bdb_add: o=client,ou=Organizations,o=companyName,ou=relations,dc=xxx,dc=yy,dc=zz slapd[3418]: send_ldap_result: err=64 matched="" text="value of naming attribute 'o' is not present in entry" where the ldif added is: [0] => dn: o=client,ou=Organizations,o=companyName,ou=relations,dc=xxx,dc=yy,dc=zz [1] => objectClass: top [2] => objectClass: Organization [3] => deleted: FALSE [4] => o: client:companyName [5] => cn: test test test What I'm I doing wrong? Can't you have two 'o=' attributes in a DN? And why does it complain about a missing attribute 'o', when in fact is looks to be there? Thanks, -- Met vriendelijke groet, R.

CRL Certificate
by Turbo Fredriksson 08 Nov '06

08 Nov '06

I've been playing with OpenSwan the last week and learned how to revoke certificates in the process. Usage of the CRL cert... In my slapd.conf's I have: TLSCACertificateFile /etc/ldap/cacert.pem TLSCertificateFile /etc/ldap/ldapsrv?_domain_tld.pub TLSCertificateKeyFile /etc/ldap/ldapsrv?_domain_tld.prv TLSVerifyClient try Where would the CRL cert fit in this? From what I can tell of the man page, nowhere. I have authentication with X.509 certificates enabled (not that anyone's using that at the moment, but...) so I would like the chance of making sure to reject revoked certificates...

Error from replica getting changes from master server
by Manuel Molina Cuberos 08 Nov '06

08 Nov '06

Hello all! Here at Ya.com we have a structure of directory service based on OpenLDAP 2.0.27. There's ldapm01, the master server, and three replicas. We want to add a new replica (smtpmaq) running OpenLDAP 2.3.27 with bdb backend, populated thru slapcat / slapadd. Our purpose is to migrate all servers to the new version. All this worked fine, but now we get the following error in the new replica: Nov 8 13:09:16 smtpmaq slapd[23815]: conn=0 op=3093 ADD dn="mailID=ya9999999(a)ya.com,ou=ya.com,o=XXXXXX" Nov 8 13:09:16 smtpmaq slapd[23815]: conn=0 op=3093 RESULT tag=105 err=20 text=attribute 'objectClass' provided more than once When we add a new entry, we do the following at the master server: dn: mailID=ya9999999(a)ya.com,ou=ya.com,o=XXXXXX changetype: add mailID: ya9999999(a)ya.com mailHost: ya.com userPassword:: XXXXXXXXXXXX= mailMessageStorePath: /some/disk/path mailStatus: 1 mailServices: 0000000000001000 [...] objectClass: mailClass objectClass: top Some notes: -The server, running the old version, works fine with this. The old replicas also work fine with this. -The new replica refuse this kind of changes, but accept any other kind of operations. -If I try something like: ... objectClass: mailClass ... without "objectClass: top", the master server and all the replicas accept the change. What do you think about instantiating only mailClass in the new entries ? Are we doing something wrong ? -- Regards, Manuel Molina Cuberos ya.com Internet Factory 91 141 7931

Problem with ACL's: can't bind as a non-root DN
by Frank Van Damme 08 Nov '06

08 Nov '06

Hello list, I am a sysadmin with limited experience with LDAP, and I am having a little issue with ACL's on an openldap server. The server has been running for more than a year as an auth. backend for Plone. However, recently I wanted to use the same user name/password information for other purposes and then I ran into a problem: I can not bind to the server as a non-root DN. More concrete example: # ldapsearch -D "cn=my_own_user_id,dc=example,dc=be" -x (&(cn=editors)(uniqueMember=cn=someuser,dc=example,dc=be))" -W Enter LDAP Password: ldap_bind: Invalid credentials (49) I'll paste the acl's from my slapd.conf file: access to attrs=userPassword by dn="cn=admin,dc=example,dc=be" write by anonymous auth by self write #by * none #access to dn.base="" by * read access to * by dn="cn=admin,dc=example,dc=be" write by dn="cn=admin,dc=example,dc=be" read by * read I would think that normally, "by anonymous auth" would allow any user (inetOrgPerson) to bind to the server? Can anyone help? Thanks in advance. -- Frank Van Damme "All PCs are compatible. But some of them are more compatible than others." [Onbekend]
