Re: access to ldap backups

[Vincent M. <Vin...@un...>]

The patch doesn't work.
I propose another patch (diff LDAP.pm file from LDAP.pm) which works in the same way that the other API LDAP (netscape, openldap, perldap Mozilla, ...) 

Following syntaxes are possible: 

Net::LDAP->new(ldap.univ.fr);  -> ldap on port 389
Net::LDAP->new(ldap.univ.fr, port => 392);  -> ldap on port 392
Net::LDAP->new(ldap.univ.fr:392);  -> ldap on port 392
Net::LDAP->new(ldap.univ.fr:392, port => 395);  -> ldap on port 392
Net::LDAP->new(ldap.univ.fr, ldap2.univ.fr);  -> ldap on port 389, then ldap2 on port 389 if impossible connection on ldap:389
Net::LDAP->new(ldap.univ.fr, ldap2.univ.fr, port => 395);  -> ldap on port 395, then ldap2 on port 395 if impossible connection on ldap:395
Net::LDAP->new(ldap.univ.fr:392, ldap2.univ.fr);  -> ldap on port 392, then ldap2 on port 389 if impossible connection on ldap:392
Net::LDAP->new(ldap.univ.fr:392, ldap2.univ.fr:395);  -> ldap on port 392, then ldap2 on port 395 if impossible connection on ldap:392
Net::LDAP->new(ldap.univ.fr:392, ldap2.univ.fr, port => 395);  -> ldap on port 392, then ldap2 on port 395 if impossible connection on ldap

The other options are available.
