Hi

I'm trying to develop configuration which includes Active Directory catalogue
into main LDAP tree I have in my configuration. Everything works well while
using slapd-meta as long as I do not try to combine it with rwm overlay.

LDAP crashes while invoking modrdn change (refer to attached crashme.ldif) with
the configuration as in config.ldif.

modrdn change works well until I add dn:
olcOverlay={0}rwm,olcDatabase={1}meta,cn=config to the configuration.

I'm using OpenLDAP 2.4.42 installed from Ubuntu repositories (latest version
from 16.04.01). 
I have uploaded ftp://ftp.openldap.org/incoming/Jaroslaw-Wencel-170315.tgz to
the ftp server, archive file contains:
- config.ldif - dump of ldap configuration from the moment modrdn operation
crashes the server
- crashme.ldif - the ldif file I'm using for invoking modrdn operation
- crash.logs - slapd daemon log

Please let me know if you have any further questions

Thanks
Jaroslaw Wencel

Hi,

Thanks for the report! There are a number of known existing issues with 
slapo-rwm, so the detail provided here is quite useful.

Regards,
Quanah

Invalid configuration, rwm should not be combined with back-meta.

Future work: Abort slapd if such an invalid configuration is encountered.
