37 contains the information necessary to configure the TACACS+ client

44 single TACACS+ server which is to be used by the library.
46 white space is ignored, as are empty lines and lines containing
49 A TACACS+ server is described by two to four fields on a line.
51 fields are separated by white space.
54 character at the beginning of a field begins a comment, which extends
55 to the end of the line.
56 A field may be enclosed in double quotes,

67 The first field specifies
68 the server host, either as a fully qualified domain name or as a
69 dotted-quad IP address.
70 The host may optionally be followed by a

80 of characters, though it must be enclosed in double quotes if it
81 contains white space or is empty.
