Re: [webmin-l] Migrating users from one system to another

[Carlton T. <ca...@gi...>]

Jamie,

Thanks for the reply. I have implemented it but I am having a
problem with the Perl modules. The problem seems to be caused
by the fact that the program does not have all the context
information correctly configured.

As an example, the line:

   &foreign_require("useradmin", "user-lib.pl");

causes the program to generate the error message:

  "module useradmin does not exist"

but if I replace that with:

  require 'useradmin/user-lib.pl';

it gets past that point OK.

Also:

  &useradmin::making_changes();

causes the error:

  Undefined subroutine &useradmin::making_changes called...

but removing the module name (ie. useradmin::), the call to
making_changes works OK.

By making changes to my program I can get Perl to satisfy all
the direct references. However, those indirect references to
Perl modules made by the Webmin functions I call are failing
with similar error messages.

Thanks in advance for any help you can provide.

Regards !
