I installed mysql 5 on a MS-XP machine running apache 1.3 and php 4. When a php script attempts to connect to mysql using [!--coloro:#FF0000--][span style=\"color:#FF0000\"][!--/coloro--]mysql_connect($host, $user, $pass)[!--colorc--][/span][!--/colorc--] the following error appears: [!--coloro:#FF0000--][span style=\"color:#FF0000\"][!--/coloro--]mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL[!--colorc--][/span][!--/colorc--] ... When I use the same hostname, username and password via the commandline or from a GUI frontend, the connection works as it should. What may be wrong?
