[rt-users] rt-3.8.1 cannot get ExternalAuth.pm to be recognized in perl's @inc list

Wed Dec 10 09:37:21 EST 2008

Remove all ExternalAuth code so that it authenticates against the 
database.  It needs to first create the default users in RT.  Once the 
make initialize-database is done, then add the ExternalAuth into 
RT_SiteConfig.pm and you'll be great.
