#include <radcli/>

int rc_aaa_ctx_server(
    rc_handle        *rh,
    RC_AAA_CTX      **ctx,
    SERVER           *aaaserver,

Like rc_aaa_ctx() but sends to aaaserver instead of the server list from the configuration. Use this when the caller has already selected the server (e.g., in proxy scenarios).

a handle to parsed configuration.
if non-NULL, receives an allocated RC_AAA_CTX on success; the caller must free it with rc_aaa_ctx_free(). Pass NULL if not needed.
a non-NULL SERVER describing the target server(s).
AUTH to use the authentication port, ACCT for the accounting port. Under TLS/DTLS only AUTH is valid (both auth and acct share the same TLS connection to the authserver).
the physical NAS port number to include (may be zero).
VALUE_PAIR list of attributes to send (e.g., PW_USER_NAME).
on success, receives the server's reply VALUE_PAIR list; the caller must free it with rc_avpair_free().
if non-NULL, must point to a buffer of PW_MAX_MSG_SIZE bytes; will contain the concatenation of any PW_REPLY_MESSAGE attributes received.
if non-zero, PW_NAS_PORT is added to the sent pairs.
one of the standard RADIUS codes (e.g., PW_ACCESS_REQUEST).

OK_RC (0) on success, CHALLENGE_RC (3) on Access-Challenge, REJECT_RC (2) on Access-Reject, or a negative error code on failure.
