Hmm, could be because the SASL RPM is built against db 4.4.20 and OpenLDAP is built against BDB 4.5.20 in /opt/bdb-4.5. I'll check that. Ciao, Michael.

Given that this particular rwm invocation isn't doing anything, it should be easy enough to just comment it out and see if the problem still occurs.

It works now, thanks. I'll commit the patch, but I think we should definitely move the cookie stuff to the frontend and generalize the cookie stuff to use bervals before we close this ITS. p. Ing.

That's strange though, as I merely followed the slapd-ldap(5) man page: suffixmassage, map, rewrite* These directives are no longer supported by back-ldap; their functionality is now delegated to the rwm overlay. Essentially, add a statement overlay rwm first, and prefix all rewrite/map statements with rwm- to obtain the original behavior. See slapo-rwm(5) for details. Maybe a man page patch is needed to stop others hitting this. Thanks. -- Kind Regards, Gavin Henry. Managing Director.
