Other Notes

AuthType DACS and the Require directive Limitations on CGI arguments
DACS advisory Potential password logging when debugging

Tips

AuthType DACS and the Require directive Omitting braces in a variable reference
Begin by reviewing dacs.quick(7) Potential password logging when debugging
Begin with a basic DACS install Problems while building with shared libraries
Building standalone components Redirection after authentication
Built-in authentication modules Remember to make public files accessible
Built-in roles modules Remember to restart httpd
CAS protocol Reviewing build notes
Configuration of mod_ssl in httpd.conf Rotate log files
Configuring HTTP authentication Save your config.nice
DACS advisory Selecting characters and substrings
DACS self tests Selecting new credentials
DEFAULT_JURISDICTION environment variable Short links
Displaying CGI arguments Testing LDAP authentication
Displaying DACS environment variables Testing NTLM authentication
Domain attributes in cookies Testing where a client authenticated
Easier upgrades Try dacsexpr
Escaping space characters Use site.conf-std
Failed internal HTTP requests Using dacsinit
Filename suffixes for CGI programs Using user()
Filenames for rulesets Validating ruleset syntax
Generated directory listings, internal redirects Value of an if statement
How to choose better passwords Variable substitution in dacs_transform
InfoCard authentication using an expression Verify web server version
Initial configuration using dacsinit Viewing DACS documentation via Apache
Installing a subset of DACS Whitespace in a variable reference
Limitations on CGI arguments dacs_transform and the 'insert' directive
Obtaining Berkeley DB local_unix_authenticate and setuid
