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 +-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-- | 85 | n | a1 | a2 | a3 | a4 | a1 | a2 | a3 | a4 | ... +-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-- 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.
