krb5_error_code krb5_get_init_creds_opt_set_expire_callback(krb5_context context, krb5_get_init_creds_opt *opt, krb5_expire_callback_func cb, void *data)¶
- param:
[in] context - Library context
[in] opt - Options structure
[in] cb - Callback function
[in] data - Callback argument
Set a callback to receive password and account expiration times.
cb will be invoked if and only if credentials are successfully acquired. The callback will receive the context from the calling function and the data argument supplied with this API. The remaining arguments should be interpreted as follows:
If is_last_req is true, then the KDC reply contained last-req entries which unambiguously indicated the password expiration, account expiration, or both. (If either value was not present, the corresponding argument will be 0.) Furthermore, a non-zero password_expiration should be taken as a suggestion from the KDC that a warning be displayed.
If is_last_req is false, then account_expiration will be 0 and password_expiration will contain the expiration time of either the password or account, or 0 if no expiration time was indicated in the KDC reply. The callback should independently decide whether to display a password expiration warning.
Note that cb may be invoked even if credentials are being acquired for the kadmin/changepw service in order to change the password. It is the caller’s responsibility to avoid displaying a password expiry warning in this case.
Warning
Setting an expire callback with this API will cause krb5_get_init_creds_password()
not to send password expiry warnings to the prompter, as it ordinarily may.
