37DESCRIPTION
38 This moduule lets you use HTTP authentication with
39 Catalyst::Plugin::Authentication. Both basic and digest authentication
40 are currently supported.
41
42 When authentication is required, this module sets a status of 401, and
43 the body of the response to 'Authorization required.'. To override this
44 and set your own content, check for the "$c->res->status == 401" in your
45 "end" action, and change the body accordingly.
46
47 TERMS
48 Nonce
49 A nonce is a one-time value sent with each digest authentication
50 request header. The value must always be unique, so per default the
51 last value of the nonce is kept using Catalyst::Plugin::Cache. To
52 change this behaviour, override the
53 "store_digest_authorization_nonce" and
54 "get_digest_authorization_nonce" methods as shown below.
55
56METHODS
57 authorization_required %opts
58 Tries to "authenticate_http", and if that fails calls
59 "authorization_required_response" and detaches the current action
60 call stack.
61
62 This method just passes the options through untouched.
63
64 authenticate_http %opts
65 Looks inside "$c->request->headers" and processes the digest and
66 basic (badly named) authorization header.
67
68 This will only try the methods set in the configuration. First
69 digest, then basic.
70
71 See the next two methods for what %opts can contain.
72
73 authenticate_basic %opts
74 authenticate_digest %opts
75 Try to authenticate one of the methods without checking if the
76 method is allowed in the configuration.
77
78 %opts can contain "store" (either an object or a name), "user" (to
79 disregard %the username from the header altogether, overriding it
80 with a username or user %object).
81
82 authorization_required_response %opts
83 Sets "$c->response" to the correct status code, and adds the correct
84 header to demand authentication data from the user agent.
85
86 Typically used by "authorization_required", but may be invoked
87 manually.
88
89 %opts can contain "realm", "domain" and "algorithm", which are used
90 to build %the digest header.
91
92 store_digest_authorization_nonce $key, $nonce
93 get_digest_authorization_nonce $key
94 Set or get the $nonce object used by the digest auth mode.
95
96 You may override these methods. By default they will call "get" and
97 "set" on "$c->cache".
98
99CONFIGURATION
100 All configuration is stored in
101 "YourApp->config->{authentication}{http}".
102
103 This should be a hash, and it can contain the following entries:
104
105 store
106 Either a name or an object -- the default store to use for HTTP
107 authentication.
108
109 type
110 Can be either "any" (the default), "basic" or "digest".
111
112 This controls "authorization_required_response" and
113 "authenticate_http", but not the "manual" methods.
114
115 authorization_required_message
116 Set this to a string to override the default body content
117 "Authorization required."
118
119RESTRICTIONS
120 When using digest authentication, this module will only work together
121 with authentication stores whose User objects have a "password" method
122 that returns the plain-text password. It will not work together with
123 Catalyst::Authentication::Store::Htpasswd, or
124 Catalyst::Plugin::Authentication::Store::DBIC stores whose "password"
125 methods return a hashed or salted version of the password.
