HDB Index Corruption
by Alejandro Imass 22 Nov '10

22 Nov '10

Hi, I searched the archives of openldap-software and openldap-technical for the terms "hdb index corruption", "hdb index", and "idex" and got zero results. I have a simple master-slave setup and my indexes are getting corrupted. We have software that ties RDBMS entries with the entryUUID because the DN can change. Of course, we use moddn to avoid changing the entryUUID. So here is the set-up: old_ldap ----> new_ldap_master ------> new_ldap_slave We run a cron that scans the old_ldap and updates information on all the records on the new_ldap_master. The information is mostly the same, but the structures of the DIT differ a lot. Ok, so the first cron updates information (attributes) that have changed in the old ldap and updates the ldap master entries. Another cron searches some info in a database and may perform many moddns if people have moved from departments, etc. The new_ldap_slave is just a replica of the first, using the methods described in the docs for MirrorMode replication. All writes AFAIK are always being done in the master. Anyway, the problem is that the HDB indexes seem to be getting corrupted. That is, if I query for and entryUUID I get a DN and if I query the DN I may get another entryUUID. If I reconstruct the indexes the problem is gone. Has anyone had a similar problem? What may be causing these problems? Is it too many wirtes? Is it common pratice to reconstruct the indexes after the massive updates? Any comments greatly appreciated ! Thanks, -- Alejandro Imass

ACL short hand notation @objectClass has side effects
by Isaac Hailperin 22 Nov '10

22 Nov '10

I have again trouble understanding ACLs: Consider the following schema: objectclass ( acmeLDAP:4.2 NAME 'acmeUserLimits' DESC 'Limits for acme Users' SUP top AUXILIARY MAY ( limitMaxUserProc $ limitMaxCpuTime $ limitMaxOpenFiles $ limitMaxCorefileSize $ limitMaxStackSize $ limitMaxMemorySize $ limitMaxVirtualMemory $ limitMaxDatasegSize $ limitMaxPipeSize $ limitMaxFileLocks $ userAttrChanged ) ) and the following ACL: [...] access to dn.subtree="ou=people,ou=unix,dc=acme,dc=org" attrs=limitMaxUserProc,limitMaxCpuTime,limitMaxOpenFiles,limitMaxCorefileSize,limitMaxStackSize,limitMaxMemorySize,limitMaxVirtualMemory,limitMaxDatasegSize,limitMaxPipeSize,limitMaxFileLocks,userAttrChanged by group="cn=useradmins,ou=group,ou=unix,dc=acme,dc=org" write by group="cn=consultants,ou=group,ou=unix,dc=acme,dc=org" write by self read by * none [...] This one works, it lets users authenticate, and restricts access to the attributes mentioned. Now as the attribute list is a bit long, I thought I could replace it with the short hand notation: access to dn.subtree="ou=people,ou=unix,dc=acme,dc=org" attrs=@acmeUserLimits (since all listet attributes are only in acmeUserLimits). Unfortunatly this does not work, it blocks users from loggin in (via ssh). One time I got the message "Permissions on the password database may be too restrictive." Obviously the shorthand notation affects other attributes as well. But looking at the object class definition, I don't see why. Can any one enlighten me about this? Isaac

back-ldap core dump
by CHIROSSEL, Olivier 22 Nov '10

22 Nov '10

Hi I have to migrate from a openldap 2.3.x to openldap 2.4. During this migration phase i want my openldap 2.3.x master replicate with slurpd to my new openldap 2.4.x master mirror mode architecture with some rewriting rules for split my big directory. I configure a proxy ldap using back-ldap with slapo-rwm overlay, but operational attributes related to entry creation and modification are proxied, even when i put < lastmod off > in the conf, contrary of the man of slapd-ldap ... So i put rw-map directives in the conf for strip operationnal attributes but this kind of operation generate a core dump ... dn: neufDhcpIP=10.145.250.119,suffix=9,o=auth,dc=neuf,dc=fr changetype: modify delete: neufDhcpOption neufDhcpOption: 1;255.255.255.0 - replace: entryCSN entryCSN: 20100511215647Z#000024#00#000000 - replace: modifiersName modifiersName: cn=manager,dc=neuf,dc=fr - replace: modifyTimestamp modifyTimestamp: 20100511215647Z dn: neufDhcpIP=10.145.250.119,suffix=9,o=auth,dc=neuf,dc=fr changetype: modify add: neufDhcpOption neufDhcpOption: 1;255.255.255.128 - replace: entryCSN entryCSN: 20100511215647Z#000024#00#000000 - replace: modifiersName modifiersName: cn=manager,dc=neuf,dc=fr - replace: modifyTimestamp modifyTimestamp: 20100511215647Z Core was generated by `openldap-2.4.23/servers/slapd/slapd -F /etc/openldap/slapd-ldap.d -h ldap://10.'.

LDAP clients fail to connect with SSL enabled
by bluethundr 21 Nov '10

21 Nov '10

LDAP clients fail to connect with SSL enabled I am attempting to setup SSL/TLS support on my openLDAP 2.4 server on FreeBSD. LBSD2# pkg_info | grep openldap openldap-sasl-client-2.4.23 Open source LDAP client implementation with SASL2 support openldap-sasl-server-2.4.23 Open source LDAP server implementation I put my cert file, key file and CA certfile in a directory called /usr/local/etc/openldap/cacerts Here's how it looks: [root@LBSD2:/usr/local/etc/openldap/cacerts]#ls -l total 48 dr--r----- 2 root ldap 512 Nov 21 17:12 bak -r--r----- 1 root ldap 1960 Nov 21 07:05 bsd2.summitnjhome.com.crt -r--r----- 1 root ldap 4604 Nov 21 17:16 gd_bundle.crt -r--r----- 1 root ldap 4689 Nov 21 18:59 sf_bundle.crt -r--r----- 1 root ldap 1537 Nov 21 17:16 sf_issuing.crt -r--r----- 1 root ldap 1090 Nov 21 12:29 slapd.csr -r--r----- 1 root ldap 1743 Nov 21 12:26 slapd.key -r--r----- 1 root ldap 1675 Nov 21 17:25 slapd.pem My cert flie is a GoDaddy turbo-ssl certfile named bsd2.summitnjhome.com.crt. slapd.key is the key file and slapd.pem is the same thing only with the password removed. I'm a little unsure of which CA file to use but I think that sf_issuing.crt _should_ work as this is the CA file that I used to setup a similar SSL enabled LDAP server for a client recently. Although I have tried all three CA files in this directory: (gd_bundle.crt, sf_bundle.crt, and sf_issuing.crt). I put the various cert/key files into my slapd.conf file like this: LBSD2# cat slapd.conf | grep -i tls ## TLS options for slapd TLSCipherSuite HIGH:MEDIUM:+SSLv2 TLSCertificateFile /usr/local/etc/openldap/cacerts/bsd2.summitnjhome.com.crt TLSCertificateKeyFile /usr/local/etc/openldap/cacerts/slapd.pem TLSCACertificateFile /usr/local/etc/openldap/cacerts/sf_issuing.crt Slapd restarts cleanly!

ubuntu sudoers won't talk to LDAP
by bluethundr 19 Nov '10

19 Nov '10

Hello Ubuntu On our network we have our sudoers stored in LDAP. This works fine on the CentOS 5.4 clients by placing into /etc/ldap.conf sudoers_base ou=sudoers,ou=Services,dc=example,dc=net and in /etc/nsswitch.conf we have the entry: sudoers: ldap (setting this setting to just 'ldap' instead of 'files ldap' does not render the machine unbootable as happens if you set passwd and group this way). However I am attempting to set this up on an Ubuntu 9.10 client and getting no joy so far. I have the same settings in /etc/ldap.conf and /etc/nsswitch.conf and cannot get sudoers to work. On the Ubuntu box, I can get LDAP entries by typing in getent passwd | grep ldapAccount, however when you attempt to sudo it fails: bluethundr@ubuntu3:~$ sudo bash >>> /etc/sudoers: syntax error near line 0 <<< sudo: parse error in /etc/sudoers near line 0 sudo: no valid sudoers sources found, quitting We leave our sudoers file blank intentionally in order to manage this via LDAP. Again, this problem is ONLY happening under Ubuntu and not under Centos 5.4. The only real difference that I see between the two clients is the sudo version. Could it be that under ubuntu LDAP sudo support isn't compiled in? if so how to recompile it so that it does? CentOS 5.4 sudo version: [root@ldap2 ~]# sudo -V Sudo version 1.7.2p1 Ubuntu 9.10 sudo version: root@ubuntu3:~# sudo -V Sudo version 1.7.0 [root@ldap2 ~]# sudo -V Sudo version 1.7.2p1 And here are the linkages: CentOS 5.4: [root@ldap2 ~]# ldd $(which sudo) libselinux.so.1 => /lib64/libselinux.so.1 (0x00002aaaaacc8000) libcap.so.1 => /lib64/libcap.so.1 (0x00002aaaaaee0000) libpam.so.0 => /lib64/libpam.so.0 (0x00002aaaab0e4000) libdl.so.2 => /lib64/libdl.so.2 (0x00002aaaab2f0000) libldap-2.3.so.0 => /usr/lib64/libldap-2.3.so.0 (0x00002aaaab4f4000) libc.so.6 => /lib64/libc.so.6 (0x00002aaaab72e000) libaudit.so.0 => /lib64/libaudit.so.0 (0x00002aaaaba86000) liblber-2.3.so.0 => /usr/lib64/liblber-2.3.so.0 (0x00002aaaabc9e000) libsepol.so.1 => /lib64/libsepol.so.1 (0x00002aaaabeac000) /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00002aaaac0f3000) libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x00002aaaac308000) libssl.so.6 => /lib64/libssl.so.6 (0x00002aaaac521000) libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00002aaaac76e000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00002aaaacabf000) libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 (0x00002aaaaccf7000) libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x00002aaaacf26000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00002aaaad1bb000) libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 (0x00002aaaad3bd000) libz.so.1 => /usr/lib64/libz.so.1 (0x00002aaaad5e3000) libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 (0x00002aaaad7f7000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00002aaaad9ff000) Ubuntu 9.10 bluethundr@ubuntu3:~$ ldd $(which sudo) linux-gate.so.1 => (0x00914000) libpam.so.0 => /lib/libpam.so.0 (0x00753000) libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0x00223000) libldap_r-2.4.so.2 => /usr/lib/libldap_r-2.4.so.2 (0x00fa1000) libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x004f1000) liblber-2.4.so.2 => /usr/lib/liblber-2.4.so.2 (0x00f35000) /lib/ld-linux.so.2 (0x00d75000) libresolv.so.2 => /lib/tls/i686/cmov/libresolv.so.2 (0x00345000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x008d0000) libgnutls.so.26 => /usr/lib/libgnutls.so.26 (0x00b77000) libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0x002e3000) libtasn1.so.3 => /usr/lib/libtasn1.so.3 (0x001df000) libz.so.1 => /lib/libz.so.1 (0x007d6000) libgcrypt.so.11 => /lib/libgcrypt.so.11 (0x003f3000) libgpg-error.so.0 => /lib/libgpg-error.so.0 (0x00110000) Thanks for any input you may have! -- Here's my RSA Public key: gpg --keyserver pgp.mit.edu --recv-keys 5A4873A9 Share and enjoy!!

I'm having a hard time understanding it. I'm using the latest openldap on ubuntu 10.10 and I can't pinpoint the exact master configuration syntax that sets up the provider to push changes to the consumers.

FYI, I've installed a conumser server in the dmz today using refreshOnly replication and it didn't work.

Want interesting restrictions to ldap auth on different servers to different users
by c0re 18 Nov '10

18 Nov '10

Hey all! I made simple ldap auth on my servers via pam_ldap. It's ok. Now I want to add users that can auth on several servers. BUT. I want to control on what servers user can login only on ldap server. I mean user user1 can must login only on server1,server2 and server3. And user2 can login only on server5 and server2. Theoretically It's possible to do with "pam_groupdn", set it it ldap.conf to server name and create as many groups as I have servers in openldap. Then I add users to some groups that they has to have access. I can group servers in some group like "city1_group" that contain all servers in city1 and add user to that group and it will have access to all servers in city1. May be anyone know another practice? Looking for best practice or something like it. Share your experience please. Thanks!!!
