80 PerlSetVar AuthzCapsRootdir /path/to/user/directory
81 Require cap staff important

87 # 3) Not let anyone else (such as an important non-staff member or an non-important staff member) access /protected
91 Apache2::AuthzCaps is a perl module which provides simple Apache2 capability-based authorization. It contains a PerlAuthzHandler and some utility functions.
93 The user data is stored in YAML files in a user-set directory. Set this directory using:
95 $Apache2::AuthzCaps::rootdir = "/path/to/directory"; # From perl
96 PerlSetVar AuthzCapsRootdir /path/to/directory # From Apache2 config
102 =item B<setcap>(I<$username>, I<$capability>, I<$value>)
104 If I<$value> is true, grants I<$username> the I<$capability> capability. Otherwise denies I<$username> that capability.
106 =item B<hascaps>(I<$username>, I<$cap>, ...)
108 Returns true if and only of I<$username> has ALL of the listed capabilities. Dies if I<$username> does not exist.
112 The PerlAuthzHandler for use in apache2.
