Authenticate and GatewayAuthenticate return FALSE when there are no
credentials supplied. AuthenticateEx indicates connection termination
with that return value. Handle this accordingly
the new AuthenticateEx callback has a default implementation. To not
break old clients only setting Authenticate or GatewayAuthenticate
callbacks prefer the old ones over the new one.
This PR adds a few changes so that a client is able to change the
authentication/logon type in the Authentication callback. I.e. if the
client was started without user/domain the authentication callback is
now able to activate smart card logon by setting the SmartcardLogon
setting along with csp/container/reader name.
Currently if the authentication callback returns `FALSE` the utils
function handle this as scenario as no credentials provided (returns
`AUTH_NO_CREDENTIALS)`.
This PR introduces a new `auth_status` called `AUTH_CANCELLED` that is
returned if the authentication callback returns `FALSE`. If the callback
returns `TRUE` and username or password are empty the util function will
continue to return `AUTH_NO_CREDENTIALS`.
THe PR also fixes some incorrect returns in RPC over HTTP gateway code.
This PR fixes an issue where user credentials were lost when connecting
to a farm that redirects the client.
During a redirect the connection settings were overriden by the settings
stored in `rdp->originalSettings`. However these settings miss any
credentials the user provides during the connection phase, thus causing
another authentication prompt to appear.
* Fixed remdesk settings pointer
* Fixed sign warnings in display_write_monitor_layout_pdu
* Use freerdp_abort_connect_context and freerdp_shall_disconnect_context
* Added and updates settings
* info assert/dynamic timezone
* mcs assert/log/flags
* Fixed and added assertions for wStream
* Unified stream length checks
* Added new function to check for lenght and log
* Replace all usages with this new function
* Cleaned up PER, added parser logging
* Cleaned up BER, added parser logging
* log messages
* Modified Stream_CheckAndLogRequiredLengthEx
* Allow custom format and options
* Add Stream_CheckAndLogRequiredLengthExVa for prepared va_list
* Improved Stream_CheckAndLogRequiredLength
* Now have log level adjustable
* Added function equivalents for existing logger
* Added a backtrace in case of a failure is detected
* Fixed public API input checks
* Early return authenticate if TLS smartcard logon
* Removed obsolete SmartcardPin and unified AuthenticateEx calls
* Remove password-is-pin from command line
The setting is implied by smartcard-logon and only of interest in
server side code, so the setting is useless
* Rework AUTH_SMARTCARD_PIN
Just prompt for PIN and not user/domain if this is requested.
* Fixed a memory leak in nla.c
* Align credentail prompt
* Handle AUTH_NLA & smartcard, just ask for PIN
* Added assertions, removed duplicate password prompt check
* Move smartcard logon after credential prompt
If freerdp_abort_connect is called, set FREERDP_ERROR_CONNECT_CANCELLED
This way freerdp_reconnect can distinguish between network issues and
user interaction and abort a retry attempt.
