I want to use the openldap smbk5passwd overlay for syncing my ldap and samba passwords. whenever I enable it openldap won't start anymore. after adding -d 31 to the /etc/conf.d/slapd OPTS I get the following messages: ------------------------------------------------ * Starting ldap-server ... @(#) $OpenLDAP: slapd 2.3.30 (Jan 24 2007 19:23:19) $ root@gauss2:/var/tmp/portage/openldap-2.3.30-r2/work/openldap-2.3.30/servers/slapd daemon_init: <null> daemon_init: listen on ldap:/// daemon_init: 1 listeners to open... ldap_url_parse_ext(ldap:///) daemon: IPv6 socket() failed errno=97 (Address family not supported by protocol) daemon: listener initialized ldap:/// daemon_init: 2 listeners opened slapd init: initiated server. slap_sasl_init: initialized! bdb_back_initialize: initialize BDB backend bdb_back_initialize: Sleepycat Software: Berkeley DB 4.2.52: (December 3, 2003) >>> dnNormalize: <> <<< dnNormalize: <> >>> dnNormalize: <cn=Subschema> => ldap_bv2dn(cn=Subschema,0) <= ldap_bv2dn(cn=Subschema)=0 => ldap_dn2bv(272) <= ldap_dn2bv(cn=subschema)=0 <<< dnNormalize: <cn=subschema> bdb_db_init: Initializing BDB database /lib/rcscripts/sh/rc-daemon.sh: line 229: 15848 Speicherzugriffsfehler /sbin/start-stop-daemon '--start' '--quiet' '--pidfile' '/var/run/openldap/slapd.pid' '--exec' '/usr/lib/openldap/slapd' '--' '-u' 'ldap' '-g' 'ldap' '-d' '31' ------------------------------------------------ Speicherzugriffsfehler = Segmentation Fault (german locale) Reproducible: Always Steps to Reproduce: 1.activate smbk5passwd 2./etc/init.d/slapd start 3.segmentation fault Actual Results: openldap crashes Expected Results: openldap should start and smbk5passwd should synchronize my passwords My slapd.conf looks like this: ------------------------------------------------------ # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/samba.schema include /etc/openldap/schema/krb5-kdc.schema # Define global ACLs to disable default read access. # Do not enable referrals until AFTER you have a working directory # service AND an understanding of referrals. #referral ldap://root.openldap.org pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args # Load dynamic backend modules: modulepath /usr/lib/openldap/openldap moduleload smbk5pwd.so # moduleload back_bdb.la # moduleload back_ldap.la # moduleload back_ldbm.la # moduleload back_passwd.la # moduleload back_shell.la authz-regexp uid=([^,]*),cn=([^,]*),cn=auth uid=$1,ou=people,dc=physik,dc=uni-marburg,dc=de # Sample security restrictions # Require integrity protection (prevent hijacking) # Require 112-bit (3DES or better) encryption for updates # Require 63-bit encryption for simple bind #security ssf=1 update_ssf=112 simple_bind=64 # Sample access control policy: # Root DSE: allow anyone to read it # Subschema (sub)entry DSE: allow anyone to read it # Other DSEs: # Allow self write access # Allow authenticated users read access # Allow anonymous users to authenticate # Directives needed to implement policy: access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to * by self write by users read by anonymous auth # # if no access controls are present, the default policy # allows anyone and everyone to read anything but restricts # updates to rootdn.

Seems to work here with hdb backend. Please retry with it instead of bdb
Could you please post your working config/use-flags? I'd like to try if it works for me too to track down the reason for the segfaults.
The problem seems to be in the kerberos part of the smbk5passwd-module because it disappeared after removing -DDO_KRB from the ebuild-file. Could you please change the ebuild that it only adds this option if the kerberos-use-flag is set? The reason is not that kerberos would be missing. It is installed but not configured in my installation. So my suggestion is only a workaround for people only using the samba-part. Is is necessary to have a running kerberos in order to use this module or should it work anyway?
well I always assume that people only set useflags if they intend to actually use that piece and have it configured ;) already collecting issues for a -r1 release. your solution is noted for it now
meh, there should be a better option to resolve a bug with other reason
Fixed in 2.3.34-r1 :=) thanks for reporting
