Testing a connection

Every method page carries the same test panel at the bottom: Test database access (using above credentials) — LAN_ALT_40 + LAN_ALT_41.

Field	LAN key	Notes
Username	LAN_ALT_33	Optional. Leave both boxes empty to test only the connection.
Password	LAN_ALT_34	Optional.
Test	LAN_ALT_47	Runs the test immediately, against the values currently saved on this page.

Help text on the panel: "If a username and password are entered, that user will also be validated" (LAN_ALT_42).

Reading the result

Result	Meaning
Authentification successful (LAN_ALT_58)	Green. Any values the source returned for this user are listed underneath (LAN_ALT_59) — this is the quickest way to see what the field mapping actually produces.
… invalid user (LAN_ALT_55)	Connection fine, username unknown to the source.
… bad password (LAN_ALT_56)	Connection fine, username known, password wrong.
… could not connect to DB / service provider (LAN_ALT_54)	Check server, port, credentials, firewall.
… method not available (LAN_ALT_57)	The required PHP extension is not loaded (LDAP / RADIUS).
… unknown cause (LAN_ALT_53)	Anything else. Any error text returned by the driver is shown below the result.

Always test before selecting the method as the primary type on Main configuration. A green result with an empty username proves the connection; a green result with a real username proves the whole path, mapping included.

The test does not create or update the local e107 user. It only validates. The local record is written during a real login.
