Hello,

Has anyone here encountered an issue with MDB and taking a slapcat of a
subtree? slapcat works fine when issued on the root DN; however it fails
when exporting a subtree as follows:
/usr/local/sbin/slapcat -F /usr/local/etc/openldap/verf/slapd.d -l
/dv01/app/OpenLDAP/verf/ldif/out.ldif -s ou=uit,o=myorg.ca

The OS is RHEL 5.8; gcc output is: gcc version 4.1.2 20080704 (Red Hat
4.1.2-52)
The exact same command works fine on BDB. Thanks for any info.

cheers,

Ven
