krb5_tkt_creds_init - Create a context to get credentials from a KDC’s Ticket Granting Service.

krb5_error_code krb5_tkt_creds_init(krb5_context context, krb5_ccache ccache, krb5_creds * creds, krb5_flags options, krb5_tkt_creds_context * ctx)

[in] context - Library context

[in] ccache - Credential cache handle

[in] creds - Input credentials

[in] options - Options (see KRB5_GC macros)

[out] ctx - New TGS request context

  • 0 Success; otherwise - Kerberos error codes

This function prepares to obtain credentials matching creds , either by retrieving them from ccache or by making requests to ticket-granting services beginning with a ticket-granting ticket for the client principal’s realm.

The resulting TGS acquisition context can be used asynchronously with krb5_tkt_creds_step() or synchronously with krb5_tkt_creds_get(). See also krb5_get_credentials() for synchronous use.

Use krb5_tkt_creds_free() to free ctx when it is no longer needed.
