| | 21 | +/** |
| | 22 | + * This class supports authentication against an external MediaWiki database, |
| | 23 | + * probably any version back to 1.5 or something. Example configuration: |
| | 24 | + * |
| | 25 | + * $wgExternalAuthType = 'MediaWiki'; |
| | 26 | + * $wgExternalAuthConf = array( |
| | 27 | + * 'DBtype' => 'mysql', |
| | 28 | + * 'DBserver' => 'localhost', |
| | 29 | + * 'DBname' => 'wikidb', |
| | 30 | + * 'DBuser' => 'quasit', |
| | 31 | + * 'DBpassword' => 'a5Cr:yf9u-6[{`g', |
| | 32 | + * 'DBprefix' => '', |
| | 33 | + * ); |
| | 34 | + * |
| | 35 | + * All fields must be present. These mean the same things as $wgDBtype, |
| | 36 | + * $wgDBserver, etc. This implementation is quite crude; it could easily |
| | 37 | + * support multiple database servers, for instance, and memcached, and it |
| | 38 | + * probably has bugs. Kind of hard to reuse code when things might rely on who |
| | 39 | + * knows what configuration globals. |
| | 40 | + * |
| | 41 | + * If either wiki uses the UserComparePasswords hook, password authentication |
| | 42 | + * might fail unexpectedly unless they both do the exact same validation. |
| | 43 | + * There may be other corner cases like this where this will fail, but it |
| | 44 | + * should be unlikely. |
