Authentication CONTINUE Packet
The Oracle® Enterprise Session Border Controller, acting as a TACACS+ client, sends an authentication CONTINUE packet to the TACACS+ daemon in response to a REPLY message which requested additional data required by the authenticator.
The authentication CONTINUE packet format is as follows.
+-----------------------------------+ | Common Header | | | | type contains 0x1 | +--------+--------+-----------------+ | user_msg_len | data_len | |--------+--------+-----------------+ | flags | user_msg ... | +--------+--------------------------+ | data ... | +-----------------------------------+
user_msg_len
This 16-bit field contains the length of the user_msg field in octets.
data_len
This 16-bit field contains the length of the data field in octets. As the data field is not used in the current TACACS+ authentication implementation, the data field always contains a value of 0 as specified in Section 4 of the TACACS+ draft RFC.
flags
This 8-bit field contains various flags that are not under user control.
user_msg
This variable length field contains a string that responds to an information request contained in a REPLY message.
data
This optional variable length field contains miscellaneous data, often in response to a daemon request. The current TACACS+ authentication implementation does not use the data field in Authentication CONTINUE packets.
