DHCP Options for Novell Directory Services
Alternative Format: Original Text Document
RFC 2241 DHCP Options November 1997
The NDS Tree Name Option and the NDS Context Option carry 16-bit
Unicode text encoded into an octet stream using UTF-8 [4]. A complete
DHCP implementation can represent of the entire Unicode character set
supported by NDS. At the same time, 7-bit ASCII text is unchanged by
the UTF-8 transformation. In environments where the NDS tree name and
context are restricted to the range of 7-bit ASCII characters, ASCII-
only DHCP clients and servers can support these options by using the
ASCII text as the UTF-8 encoded data.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119. [2]
2. NDS Servers Option
This option specifies one or more NDS servers for the client to
contact for access to the NDS database. Servers SHOULD be listed in
order of preference.
The code for this option is 85. The minimum length of this option is
4 octets, and the length MUST be a multiple of 4.
Code Len Address 1 Address 2

3. NDS Tree Name Option
This option specifies the name of the NDS tree the client will be
contacting. NDS tree names are 16-bit Unicode strings. For
transmission in the NDS Tree Name Option, an NDS tree name is
transformed into octets using UTF-8. The string should NOT be zero
terminated.
The code for this option is 86. The maximum possible length for this
option is 255 bytes.
