For 3.6.0, the idmap:script parameter (which belongs to the tdb2 idmap backend) was deprecated in favour of the more systematic "idmap config * : script".
There is a bug in the code change though, which defaults the "idmap config * : script" to "NULL" (string) instead of NULL (null pointer).
This lets the fallback to the idmap:script parameter fail.
It also leads to vain attempts to call out to a script called "NULL" when unmapped sids are found.
