unable to load back-perl module

[Benin Technologies <benintechnologies@yahoo.fr>]

Hi,

I'm unable to load the back-perl backend module, I get "lt_dlopenext 
failed: (back_perl.la) file not found"

But back_perl.la is there though, and I can load other modules without 
problem (back_hdb.la, back_sql.la, ...)

Any idea what's going on ?

My slapd.conf :
# Load dynamic backend modules:
modulepath      /usr/local/libexec/openldap
moduleload      back_hdb.la
moduleload      back_sql.la
moduleload      back_perl.la

If I comment the last line, slapd starts without problem.


The error message :
root@ldap:~# /usr/local/libexec/slapd -u openldap -g openldap -d 256
514dbea0 @(#) $OpenLDAP: slapd 2.X (Feb  3 2013 19:41:33) $
    root@ldap:/tmp/openldap-a98eb28/servers/slapd
514dbea0 lt_dlopenext failed: (back_perl.la) file not found
514dbea0 slapd stopped.
514dbea0 connections_destroy: nothing to destroy.


It doesn't find back_perl.la, but the file exists though, with the same 
right as the other backend modules:
root@ldap:/usr/local/libexec/openldap# ls -la
-rwxr-xr-x 1 root staff     987 Feb  3 19:43 back_hdb.la
-rwxr-xr-x 1 root staff    1026 Feb  3 19:43 back_perl.la
-rwxr-xr-x 1 root staff     991 Feb  3 19:43 back_sql.la

I'm using OpenLDAP 2.4.33 on Debian 6.0.4

Ben.
