[Pkg-openldap-devel] Bug#667009: slapd segfaults if configured with back-sql and slapd.conf style configuration

[Lior Okman]

Package: slapd
Version: 2.4.28-1.1
Severity: important

Dear Maintainer,

I've installed slapd, and reconfigured it to use the back-sql backend, using PostgreSQL 9.1 as the RDBMS.
The schema I am using is the one provided in the upstream tarball (used by the slapd automatic tests).

After moving aside the /etc/ldap/slapd.d directory and providing a full and valid configuration in /etc/ldap/slapd.conf,
the slapd server segfaults, without anything relevant in the logs, and also without a core dump (ulimit -c is set to unlimited).

Running '/usr/sbin/slapd -Tt' also causes a segmentation fault, and this time a core dump is created. When running this core
through gdb, it appears as if there's an endless recursion going on while parsing the configuration file. The stack trace for the
active thread contains 622 frames.

The outcome is that the back-sql backend is not usable since slapd can't be started with this backend.
