rc_aaa_ctx_server(3)

NAME
rc_aaa_ctx_server - Builds an authentication/accounting request and submits it to a specific server.

SYNOPSIS
#include <radcli/>

int rc_aaa_ctx_server(
    rc_handle        *rh,
    RC_AAA_CTX      **ctx,
    SERVER           *aaaserver,
    rc_type           type,
    uint32_t          nas_port,
    VALUE_PAIR       *send,
    VALUE_PAIR      **received,
    char             *msg,
    int               add_nas_port,
    rc_standard_codes request_type
);

DESCRIPTION

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).

PARAMETERS

rh  a handle to parsed configuration.

ctx 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.

aaaserver
    a non-NULL SERVER describing the target server(s).

type
    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).

nas_port
    the physical NAS port number to include (may be zero).

send
    VALUE_PAIR list of attributes to send (e.g., PW_USER_NAME).

received
    on success, receives the server's reply VALUE_PAIR list; the caller must free it with rc_avpair_free().

msg 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.

add_nas_port
    if non-zero, PW_NAS_PORT is added to the sent pairs.

request_type
    one of the standard RADIUS codes (e.g., PW_ACCESS_REQUEST).

STRUCTURES

Avoid using this structure directly, it is included for backwards compatibility only. Several of its fields have been deprecated.

    struct server {
      int      max;
      char    *name[RC_SERVER_MAX];
      uint16_t port[RC_SERVER_MAX];
      char    *secret[RC_SERVER_MAX];
      double   deadtime_ends[RC_SERVER_MAX]; // unused
    };

Avoid using this structure directly. Use rc_avpair_get_uint32() for integer/IPv4/date values, rc_avpair_get_in6() for IPv6 addresses and prefixes, rc_avpair_get_raw() for string/binary values, and rc_avpair_get_attr() to read the attribute type and ID. To iterate the list use rc_avpair_next(). Free the entire list with rc_avpair_free().

    struct rc_value_pair {
      char                   name[RC_NAME_LENGTH+1];      // attribute name if known.
      uint64_t               attribute; // attribute numeric value of type rc_attr_id including vendor; use VENDOR() and ATTRID() to separate.
      rc_attr_type           type;      // attribute type.
      uint32_t               lvalue;    // attribute value if type is PW_TYPE_INTEGER, PW_TYPE_DATE or PW_TYPE_IPADDR.
      char                   strvalue[AUTH_STRING_LEN+1];  // contains attribute value in other cases.
      struct rc_value_pair  *next;
      char                   pad[32];       // unused pad
    };

Avoid using this structure directly. Use rc_avpair_get_uint32() for integer/IPv4/date values, rc_avpair_get_in6() for IPv6 addresses and prefixes, rc_avpair_get_raw() for string/binary values, and rc_avpair_get_attr() to read the attribute type and ID. To iterate the list use rc_avpair_next(). Free the entire list with rc_avpair_free().

    struct rc_value_pair {
      char                   name[RC_NAME_LENGTH+1];      // attribute name if known.
      uint64_t               attribute; // attribute numeric value of type rc_attr_id including vendor; use VENDOR() and ATTRID() to separate.
      rc_attr_type           type;      // attribute type.
      uint32_t               lvalue;    // attribute value if type is PW_TYPE_INTEGER, PW_TYPE_DATE or PW_TYPE_IPADDR.
      char                   strvalue[AUTH_STRING_LEN+1];  // contains attribute value in other cases.
      struct rc_value_pair  *next;
      char                   pad[32];       // unused pad
    };

RETURN VALUE

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