This is perl, v5.8.8 built for i486-linux-gnu-thread-multi ------------
Hello, I got the above error, when I try to start slapd, with perl backends, and some "use" lines in script. No matter what perl package I try to use (POSIX, DBI, whatever), I get similar error regarding perl library.
I tried to rebuild perl and its modules, and rebuild openldap (tried 2.3.30 and 2.3.35 versions), with no effect. Is there some limitation on perl backend, because of kind of the way it's embedded into slapd, which actually disallow usage of external modules? It seems slapd runs fine, when I don't put any "use" lines into backend perl file (*.pm) Should I try without threading, or what?
I've seen this thing being reported a few times on various lists, including some linux distribution bugzillas, anyway there was no answer, see e.g. this https://bugs.launchpad.net/ubuntu/+source/openldap2.2/+bug/90812
This slapd 2.3.35 was built with the following options:
--prefix=/usr --libexecdir=/usr/lib --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --enable-debug --enable-dynamic --enable-syslog --enable-proctitle --enable-ipv6 --enable-local --enable-slapd --enable-aci --enable-cleartext --enable-crypt --enable-spasswd --enable-modules --enable-rewrite --enable-rlookups --enable-slp --enable-wrappers --enable-backends=mod --enable-overlays=mod --enable-slurpd --with-subdir=ldap --with-cyrus-sasl --with-threads --with-tls --enable-bdb=mod --enable-dnssrv=mod --enable-hdb=mod --enable-ldap=mod --enable-ldbm=mod --enable-meta=mod --enable-monitor=mod --enable-null=mod --enable-passwd=mod --enable-perl=mod --enable-relay=mod --enable-shell=mod --enable-sql=mod --enable-accesslog=mod --enable-auditlog=mod --enable-denyop=mod --enable-dyngroup=mod --enable-dynlist=mod --enable-lastmod=mod --enable-ppolicy=mod --enable-proxycache=mod --enable-refint=mod --enable-retcode=mod --enable-rwm=mod --enable-syncprov=mod --enable-translucent=mod --enable-unique=mod --enable-valsort=mod
and the part from slapd.conf (of course the same happens with only one directory in perlModulePath, containing PerlBackend.pm)
database perl suffix "dc=example" perlModulePath /etc/ldap /usr/local/lib/perl/5.8.8 /usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl perlModule PerlBackend
"PerlBackend.pm" is the file from slapd distribution, SampleLDAP, I just renamed it.
