--- Comment #4 from Karl O. Pinc <[email protected]> ---
The problem with adding an attribute is that this means that
comments are per-entry, and cannot be associated with specific
attribute values.

Having to write comments on an entry that apply to a specific
attribute value means having to describe the attribute's value within
the comment.  Most of my comments have to do with particular attribute
values, so this would be awkward -- both for writer and reader.

Below is an alternative design.  It supports commenting both
entries and attributes and working with commented ldif files in
an "expected" way.  The downside is that this design does not
provide a "natural" user interface.  Generic LDAP clients would
not readily associate comment text with the entries or attributes
commented.  The OpenLDAP client tools would need to be used to
produce and consume "commented ldif" files.

No reason why this alternative design could not be implemented
alongside the design previously proposed.


Have a cn=comment,cn=config subtree.  The dn is
index=X,attribute=Y,EntryUUID=Z,cn=comment,cn=config.  (Where index is
the index of the commented attribute when an attribute is
multi-valued.)  Keep all the comments there.

Index and attribute would be optional in the dn; when omitted the
comment is on the entry.

Pass a flag to ldapmodify and ldapadd so that comments are preserved
on input, and a flag for ldapsearch to output such comments.
The flag would only work on the cn=config DIT.

Comments appearing in an ldif before a dn are attached to the entry.
Comments appearing before an attribute are attached to the attribute.
