[pgpool-general: 2803] Re: PgPool SSL problems: library refuses to load, even though enabled

[Rick Morris]

On more inspection, it appears that even though the pgpool RPM was linked
to the SSL library when compiled, the --with-openssl directive was not
enabled. I compiled pgpool from source with the openssl directive, and now
have no problem with SSL connections.

In the future, I hope the PgPool team will consider releasing an
SSL-enabled RPM for download, as it makes widespread deployment of PgPool
much easier in an enterprise.

Best regards,

Rick Morris
