Hello Klara,
If you add the 'use ...' before require and then run the script, do you
get debug output from IO::Socket::SSL? I have not tried this myself, but
my understanding is IO::Socket::SSL is what Net::LDAP uses for LDAPS.
If you do get debug output, you could try modifying Ldap.pm a bit more
and make it load IO::Socket::SSL with debug enabled.
When you then run radiusd with -foreground and -log_stdout options, you
should see the debug output when LDAPS connections are created.
Maybe this debug would show what goes wrong.
use IO::Socket::SSL qw(debug3);
