schema format questions

[Peter M. <pet...@ma...>]

Hi,

I have two questions about the frmat of schema entries that
may be a little off topic, but bay also affect perl-ldap:

* Is ' (single quote) legal inside qdstrings in schema definitions=20
  RFC2252 does not explicitely deny it. It simply gives the
  following definitions

      dstring         =3D 1*utf8
      qdstring        =3D whsp "'" dstring "'" whsp

  without defining utf8 further
  Since a single quote is a utf8 character, this could mean
  that single quotes inside qdstrings are really allowed.
  So
      DESC 'New Object's FS Rights'
  might be a legal description.
* Is _ (underscore) a legal character in private extensions to
  schema elements ?
   RFC2252 does not explicitely forbid it.
   It simply says:
       "Terms which begin with the characters "X-" are reserved
       for private experiments, and MUST be followed by a
        <qdstrings>"
   But no correlation is made between the word term and
   any formally defined word.
   So
      X-NDS_NOT_SCHED_SYNC_IMMEDIATE '1'
   might be a legal extension.

I do not ask this just for fun.
I find the assumptions made by Net::LDAP::Schema reasonable
(since the things above make parsing the schema quite hard).

But I have a directory server (guess which manufacturer ;-))
that contains those elements in the schema, making the schema
un-parseable by Net::LDAP::Schema.

Before I go out and tell them to correct their schema description
accordng to RFC I would like to get ohers' opinions if such a schema
conforms to RFC2252.

Last but not least, I have a very rough patch available that would allow
to parse such a schema. But I have to polish it  a bitbefore I send it.
Are you interested ?

Yours
Peter
