SASL is the Simple Authentication and Security Layer,
a method for adding authentication support to connection-based protocols.
To use SASL, a protocol includes a command for identifying and authenticating
a user to a server and for optionally negotiating protection of subsequent
protocol interactions. If its use is negotiated, a security layer is inserted
between the protocol and the connection.
To actually use SASL you must install at least one of the libsasl2-plug-XXXX
authentication plugin, such as libsasl2-plug-plain.
The SQL auxprop plugin can be rebuild with different database backends:
--with srp SRP support (disabled)
--with mysql MySQL support (enabled)
--with pgsql Postgres SQL support (disabled)
--with sqlite SQLite support (disabled)
