3.6 doesn't contain ldb tools any longer but the ldb*.1 man pages are still in the release tar ball they should be removed, too.
Fixed with commit 73e66730. Thanks for reporting! Closing out bug report.

Sorry, that has happened by accident. (Currently, 'make release' does not create the Samba3-HOWTO collection, so I rebuilt the manpages, rsynced them to the older docs and did not use the '--delete' option.) But the manpages have been removed from the docs-xml dir. So I'll close out the bug report again (and removed the ldb files manually to make sure not to use them for 3.6.1 also).
