Detailed Description

This is a short lived structure is the visible aspect of the authentication framework.

It and its children hold the state data while processing authentication for a client request. The AuthenticationStateData object is merely a CBDATA wrapper for one of these.

◆ direction()

Auth::Direction Auth::UserRequest::direction ( )

Used by squid to determine what the next step in performing authentication for a given scheme is.

Return values

CRED_ERROR	ERROR in the auth module. Cannot determine request direction.
CRED_LOOKUP	The auth module needs to send data to an external helper. Squid will prepare for a callback on the request and call the AUTHSSTART function.
CRED_VALID	The auth module has all the information it needs to perform the authentication and provide a succeed/fail result.
CRED_CHALLENGE	The auth module needs to send a new challenge to the request originator. Squid will return the appropriate status code (401 or 407) and call the registered FixError function to allow the auth module to insert it's challenge.

◆ start()

void Auth::UserRequest::start	(	HttpRequest *	request,

Start an asynchronous helper lookup to verify the user credentials

Uses startHelperLookup() for scheme-specific actions.

The given callback will be called when the auth module has performed it's external activities.

Parameters

handler	Handler to process the callback when its run
data	CBDATA for handler

static

Locate user credentials in one of several locations. Begin authentication if needed.

Credentials may be found in one of the following locations (listed by order of preference):

the source passed as parameter aUR
cached in the HttpRequest parameter from a previous authentication of this request
cached in the ConnStateData parameter from a previous authentication of this connection (only applies to some situations. ie NTLM, Negotiate, Kerberos auth schemes, or decrypted SSL requests from inside an authenticated CONNECT tunnel)
cached in the user credentials cache from a previous authentication of the same credentials (only applies to cacheable authentication methods, ie Basic auth)
new credentials created from HTTP headers in this request

The found credentials are returned in aUR and if successfully authenticated may now be cached in one or more of the above locations.

Returns: Some AUTH_ACL_* state

◆ username()

char const * Auth::UserRequest::username ( ) const

Squid does not make assumptions about where the username is stored. This function must return a pointer to a NULL terminated string to be used in logging the request. The string should NOT be allocated each time this function is called.

Return values

NULL	No username/usercode is known.
*	Null-terminated username string.

◆ valid()

bool Auth::UserRequest::valid ( ) const

Check a auth_user pointer for validity. Does not check passwords, just data sensability. Broken or Unknown auth_types are not valid for use...

Return values

false	User credentials are missing.
false	User credentials use an unknown scheme type.
false	User credentials are broken for their scheme.
true	User credentials exist and may be able to authenticate.
