MIDAS Knowledgebase

Why are required Perl modules reported missing during install?

In some instances, if a minimal or "bare bones" install of Perl has been configured in your server, some of the Perl modules required by MIDAS to function correctly may be missing.

We provide a free Server Readiness Tool that you can run on your server and that will check for any missing Perl modules prior to your install of MIDAS.

MIDAS requires the following Perl modules:

Archive::Tar
CGI
DBI
DBD::mysql
Digest::MD5
Digest::SHA
Encode
IO::Socket::SSL
JSON
LWP::Simple
LWP::UserAgent
Memoize
MIME::Base64
Time::Local
XML::Simple

The following additional modules may also be necessary depending upon your requirements:

Authen::SASL (Only required if you wish MIDAS to send email via SMTP, and your SMTP server requires SSL connections)
CGI::Carp (Only required if you intend to enable debug loggin)
Crypt::Eksblowfish (Recommended for increased security)
Excel::Writer::XLSX (Required if you wish to be able to export data from your MIDAS system in native Microsoft Excel (.xlsx) format)
Math::Random::Secure (Recommended for increased security)
Net::Config (Only required if you wish MIDAS to send email via SMTP)
Net::LDAP (Only required if you intend to enable Active Directory support)
Net::SMTP (Only required if you wish MIDAS to send email via SMTP)
Net::SMTP::SSL (Only required if you wish MIDAS to send email via SMTP, and your SMTP server requires SSL connections)
Net::SMTP::TLS (Only required if you wish MIDAS to send email via SMTP, and your SMTP server requires TLS connections)
Net::SMTPS (Only required if you wish MIDAS to send email via SMTP, and your SMTP server requires STARTTLS connections)
Time::Piece (Only required if your Perl distribution doesn't support POSIX/tzset - such as Strawberry Perl)

All these modules can be freely downloaded & installed on your server from metacpan.org.
