[Bug 478827] [NEW] openldap database backend back_perl has undefined symbols (aka slapd-perl back-perl)

[Joshua Miller]

Public bug reported:

Error when starting slapd when configured to use the perl backend (/etc/init.d/slapd start):
Starting OpenLDAP: slapd - failed:
/usr/sbin/slapd: symbol lookup error: /usr/lib/perl/5.10/auto/Fcntl/Fcntl.so: undefined symbol: Perl_Istack_sp_ptr

This may be related to bug #90812

When start fails, also verified it was not running with ps.
Removing the "database perl" section allows it to start.


lsb_release -rd
Description:    Ubuntu 9.10
Release:        9.10

slapd -V
@(#) $OpenLDAP: slapd 2.4.18 (Sep  8 2009 17:47:22) $
        buildd at crested:/build/buildd/openldap-2.4.18/debian/build/servers/slapd

To reproduce:

Changed to use slapd.conf rather than ldif configs.
/etc/defaults/slapd :
SLAPD_CONF=/etc/ldap/slapd.conf
SLAPD_USER="openldap"
SLAPD_GROUP="openldap"
SLAPD_PIDFILE=
SLAPD_SERVICES="ldap:/// ldapi:/// ldaps:///"
SLAPD_SENTINEL_FILE=/etc/ldap/noslapd
SLAPD_OPTIONS=""


My /etc/ldap/slapd.conf:
moduleload      back_perl
include         /etc/ldap/schema/core.schema
include         /etc/ldap/schema/cosine.schema
include         /etc/ldap/schema/inetorgperson.schema
loglevel       1320
pidfile        /var/run/slapd/slapd.pid
argsfile       /var/run/slapd/slapd.args
password-hash          {SSHA}
database    perl       
suffix                 "dc=company,dc=com"
perlModulePath /etc/ldap/perl
perlModule SampleLDAP


Copied SampleLDAP.pm from source distribution to /etc/ldap/perl/SampleLDAP.pm
chown'd it to openldap:
chmod'd it to 750
opendlap source location:
    openldap-2.4.19/servers/slapd/back-perl/SampleLDAP.pm

Fixed bug in SampleLDAP.pm on line 52:
    <     print {*STDERR}, "====$filterStr====\n";
    >     print {*STDERR} "====$filterStr====\n";

[note: attached the SampleLDAP.pm]


Attempt to start service, and receive the error.
/etc/init.d/slapd start
Starting OpenLDAP: slapd - failed:
/usr/sbin/slapd: symbol lookup error: /usr/lib/perl/5.10/auto/Fcntl/Fcntl.so: undefined symbol: Perl_Istack_sp_ptr
