Errors in RFC 2307 and nis.schema?
In RFC 2307 and the nis.schema file that ships with OpenLDAP, the following
two entries list "description" as both MUST and MAY. Is there a reason for
this? Doesn't the MUST clause override the MAY clause, i.e., since it is in
the MUST clause, doesn't that make it a required attribute?
( nisSchema.2.4 NAME 'ipProtocol' SUP top STRUCTURAL
DESC 'Abstraction of an IP protocol. Maps a protocol number
to one or more names. The distinguished value of the cn
attribute denotes the protocol's canonical name'
MUST ( cn $ ipProtocolNumber $ description )
MAY description )
( nisSchema.2.5 NAME 'oncRpc' SUP top STRUCTURAL
DESC 'Abstraction of an Open Network Computing (ONC)
[RFC1057] Remote Procedure Call (RPC) binding.
This class maps an ONC RPC number to a name.
The distinguished value of the cn attribute denotes
the RPC service's canonical name'
MUST ( cn $ oncRpcNumber $ description )
MAY description )
