Re: (ITS#5456) inaccurate interpretation of LDIF in back perl

[Uwe.Werler@o3si.de]

Hello Howard,

in my last message (see below) the question was not wether is an entry
starting with a blank line or not or what is a correct ldif. My question
was if back_perl is only accepting "ldif-like" entries starting with
dn-spec.

If I return an entry like this:

version: 1
dn: ou=foo,dc=bar
ou: foo
objectClass: organizationalUnit
objectClass: top
description: users from foo

or with SEP after version-spec

version: 1

dn: ou=foo,dc=bar
ou: foo
objectClass: organizationalUnit
objectClass: top
description: users from foo

then the debug output from slapd is: "str2entry: entry -1 has no dn"

That means that back_perl doesn't accept ldif files but only "ldif-like"
entries without version-spec.

If this is intended than I suggest to explain this in the man page or at
least in the example shipped with back_perl.

Thank You for Your attention.

Regards Uwe
