RE: (ITS#4849) LDAP URL not recognized with bind9
by cyril＠coupel.net 23 Feb '07

Tanks for your answer. I tested by removing the %xxxx% from the URL and the tests are passed; but there is an error saying that there is no %xxx% token. I already open a case to the BIND team, but they reply this is not a bind problem. However, I will transmit this information to the BIND/DLZ team. -----Message d'origine----- De : Pierangelo Masarati [mailto:ando@sys-net.it] Envoyé : vendredi 23 février 2007 12:56 À : Cyril COUPEL; openldap-its(a)openldap.org Objet : Re: (ITS#4849) LDAP URL not recognized with bind9 Please keep replies on the Issue Tracking System (ITS) list, otherwise you'll defeat its purpose of tracking issues.

I see the fact that earlier versions of OpenLDAP were not compliant with standard track documents as a good reason to improve it by making it compliant, rather than a reason to keep it broken. The client is broken since it appears to parse the URL __before__ replacing portions of it that are marked using a character that is invalid in URLs. Either that client implements and uses its own broken URL parsing routines (at the risk of parsing broken URLs incorrectly, since they contain invalid characters), or it does URL parsing __after__ string replacement (i.e. after their string has been turned into a valid URL). I don't see why OpenLDAP should break (or, in this case, remain broken) to maintain compatibility with a poorly implemented client. p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

(ITS#4848) Another slapd startup segfault
by michael.heep＠o2.com 22 Feb '07

Full_Name: Michael Heep Version: 2.3.34 OS: RHES30 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (82.113.101.1) Since I'm not sure whether this is realted to my previos ITS (4847) so I'm filing another report as the OS and circumstances are different. As of 2.3.34 slapd crashes on Red Hat Enterprise 3.0 during startup. The funny thing is it only crashes on our slave, not on the master. The slave uses the following slapd.conf: # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # # Schema files to include include /opt/openldap/etc/schema/core.schema include /opt/openldap/etc/schema/cosine.schema include /opt/openldap/etc/schema/sudo.schema include /opt/openldap/etc/schema/nis.schema include /opt/openldap/etc/schema/openssh-lpk.schema include /opt/openldap/etc/schema/dyngroup.schema # Put those into the 'ldap' user's homedir (/var/lib/ldap) because # user 'ldap' has no write permissions in /var/run pidfile /var/lib/ldap/slapd.pid argsfile /var/lib/ldap/slapd.args # Security restrictions (all operations require at least 128bit encryption) security ssf=128 update_ssf=128 simple_bind=128 # Access control policy # rootdn can always read/write anything! # DO NOT MESS WITH THIS UNLESS YOU KNOW WHAT YOU’ARE DOING! access to dn.subtree="cn=Monitor" by dn.children="ou=CNO-LDC,ou=People,dc=o2online,dc=de" read access to dn.subtree="cn=accesslog" by dn.children="ou=CNO-LDC,ou=People,dc=o2online,dc=de" read access to * by dn.children="ou=Area 52,dc=o2online,dc=de" none by dn.children="ou=CNO-LDC,ou=People,dc=o2online,dc=de" write by dn.exact="cn=syncreader,dc=o2online,dc=de" read by * break access to attrs=userPassword by self write by anonymous auth access to attrs=shadowLastChange by self write by * read access to * by * read # Logging loglevel 256 # Close idle connections after 120sec idletimeout 120 # SSL/TLS Stuff TLSCACertificateFile /opt/openldap/etc/ssl-certs/cno-ldc_ca.cert TLSCertificateFile /opt/openldap/etc/ssl-certs/sgmldap02.cert TLSCertificateKeyFile /opt/openldap/etc/ssl-keys/sgmldap02.key TLSCipherSuite HIGH TLSVerifyClient try # Chainig overlay for automatic referral chasing (global so it affects updaterefs!) # chain-uri must be EXACTLY the same as updateref (ip/host, port), otherwise it wont't work! overlay chain chain-uri "ldap://sgmldap01" chain-idassert-bind bindmethod=sasl binddn="cn=syncreader,dc=o2online,dc=de" saslmech=external mode=self chain-tls start ######################## # Database definitions # ######################## # Database for access logging database bdb suffix cn=accesslog rootdn "cn=root,cn=accesslog" rootpw {SSHA}FORBIDDEN directory /var/lib/ldap/openldap-accesslog # Indices to maintain index reqStart eq index objectClass eq # Checkpointing & caching checkpoint 256 5 cachesize 1000 idlcachesize 3000 # No limits for CNO-LDC limits dn.children="ou=CNO-LDC,ou=People,dc=o2online,dc=de" size=unlimited time=unlimited # Database with monitor backend for the Directory Informartion Tree database monitor database bdb suffix "dc=o2online,dc=de" rootdn "cn=root,dc=o2online,dc=de" # Cleartext passwords, especially for the rootdn, should # be avoid.
