New NIS Features in ONCplus B.11.31.04
NIS introduces the following features:
• IPv6 support for RPC commands and daemons Phase I
ONCplus B.11.31.04 delivers IPv6 support for rpc.rexd, rpc.rwalld, rpc.rusersd, rusers, and
rwall commands and daemons. Other RPC commands and daemons (rpc.statd and rpc.rquotad)
will support IPv6 in a future release of ONCplus.
NGROUPS Expansion
The NGROUPS expansion enhancement to HP-UX 11i v3 Update 3 changes the maximum number
of groups for a user or process to be a tunable parameter. This allows customers to implement
models for file access and protection that were not possible under the previous limit of 20 groups
per user. Before deploying such models, customers must update the HP-UX kernel and utilities, and
ensure that their local applications are compatible with the expanded group limit. ONCplus has
the following limitations regarding the number of groups per user:
• The records, which can be passwords, groups, hosts, netid, etc., in the NIS database are
limited to 1024 characters. The use of extremely long group names can cause the 1024
character limit to be exceeded even with just 20 groups, and in that case, such long records
will not be included in the NIS database.
• NIS builds a database containing information about user group membership, called netid.
NIS will include only the first 20 supplementary user groups in this database. This is usually
used in conjunction with ONC RPC, where only the first 16 groups are significant. NIS netid
maps will support only 20 user supplementary groups for backward compatibility.
