CentOS 4 snag with htaccess

[webmaster at ew3d.com (John Hinton)]

I'm hitting a snag with htaccess. Have created .htaccess and .htpasswd 
files, set up apache directory options just like always... the exact 
same setup works fine on CentOS 3, but I can't seem to get it to 
authenticate on CentOS 4? Am I just being blind stupid (as in not seeing 
something 'exactly the same') or is there something different I'm 
missing? I have selinux running in warn mode I think it was, but not 
fully enabled.

Best,
John Hinton
