Detailed Description

Function Documentation

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_rd_req_ctx (krb5_contextcontext, krb5_auth_context *auth_context, const krb5_data *inbuf, krb5_const_principalserver, krb5_rd_req_in_ctxinctx, krb5_rd_req_out_ctx *outctx)

The core server function that verify application authentication requests from clients.

Parameters:

context Keberos 5 context.
auth_context the authentication context, can be NULL, then default values for the authentication context will used.
inbuf the (AP-REQ) authentication buffer
server the server to authenticate to. If NULL the function will try to find any available credential in the keytab that will verify the reply. The function will prefer the server specified in the AP-REQ, but if there is no mach, it will try all keytab entries for a match. This has serious performance issues for large keytabs.
inctx control the behavior of the function, if NULL, the default behavior is used.
outctx the return outctx, free with krb5_rd_req_out_ctx_free().

Returns:

Kerberos 5 error code, see krb5_get_error_message().

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_rd_req_in_ctx_alloc (krb5_contextcontext, krb5_rd_req_in_ctx *ctx)

Allocate a krb5_rd_req_in_ctx as an input parameter to krb5_rd_req_ctx(). The caller should free the context with krb5_rd_req_in_ctx_free() when done with the context.

Parameters:

context Keberos 5 context.
ctx in ctx to krb5_rd_req_ctx().

Returns:

Kerberos 5 error code, see krb5_get_error_message().

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_rd_req_in_set_keytab (krb5_contextcontext, krb5_rd_req_in_ctxin, krb5_keytabkeytab)

Set the keytab that krb5_rd_req_ctx() will use.

Parameters:

context Keberos 5 context.
in in ctx to krb5_rd_req_ctx().
keytab keytab that krb5_rd_req_ctx() will use, only copy the pointer, so the caller must free they keytab after krb5_rd_req_in_ctx_free() is called.

Returns:

Kerberos 5 error code, see krb5_get_error_message().

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_rd_req_in_set_pac_check (krb5_contextcontext, krb5_rd_req_in_ctxin, krb5_booleanflag)

Set if krb5_rq_red() is going to check the Windows PAC or not

Parameters:

context Keberos 5 context.
in krb5_rd_req_in_ctx to check the option on.
flag flag to select if to check the pac (TRUE) or not (FALSE).

Returns:

Kerberos 5 error code, see krb5_get_error_message().

KRB5_LIB_FUNCTION void KRB5_LIB_CALL krb5_rd_req_out_ctx_free (krb5_contextcontext, krb5_rd_req_out_ctxctx)

Free the krb5_rd_req_out_ctx.

Parameters:

context Keberos 5 context.
ctx krb5_rd_req_out_ctx context to free.

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_rd_req_out_get_server (krb5_contextcontext, krb5_rd_req_out_ctxout, krb5_principal *principal)

Get the principal that was used in the request from the client. Might not match whats in the ticket if krb5_rd_req_ctx() searched in the keytab for a matching key.

Parameters:

context a Kerberos 5 context.
out a krb5_rd_req_out_ctx from krb5_rd_req_ctx().
principal return principal, free with krb5_free_principal().
