PHP & Apache

This may be slightly off topic so please forgive me, but... I am trying to get my apache server up and running with PHP and basic authentication. Everything appears to be okay except the authentication portion. When I try to access the directory requiring authentication I reciever a 500 error and the following in the web server log? Is this a configuration problem with apache and/or PHP? [Mon Apr 29 15:04:34 2002] [crit] [client XXX.XXX.XXX.XXX] configuration error: couldn't check user. No user file?: /secure My .htaccess file is as follows in the /secure directory: AuthName "G-ISAC Members Only" AuthType Basic AuthUserFile /etc/users require valid-user yes, the /etc/users file exists. I have tried changing the permissions to 777 just for testing purpose without resolve. Any help would be apprciated. Thank you. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
