Dear Maintainer,

following the instructions on https://www.debian.org/doc/manuals/debian-handbook/sect.ldap-directory.en.html led to compilation problems with perl and I got the following output: Can't locate File/Which.pm in @INC

To solve the problem I installed the package libfile-which-perl. This solved the problem and I was able to follow the instructions above.

The page
https://www.debian.org/doc/manuals/debian-handbook/sect.ldap-directory.en.html
should mention that the additional package has to be installed, or even
better, the package migrationtools should have the dependency to package
libfile-which-perl.
