RE: Splitting a DN into RDN's

[Klunder, J. (Hans) <J.A...@rf...>]

Graham and Chris,

Thanks very much for the DN splitting code. Yes it would be very nice if it
was incorporated into Net::LDAP.

Mozilla's $entry->hasValue($attribute,$value,$options) checks if the given
attribute has the given value. The options specify if case sensitivity
should be applied.

Regards,

Hans

There isn't. (Net::LDAP doesn't provide much in the way of help
manipulating values from the directory. This is a case where syntax
handlers would be nice. If I could ever get around to finishing them!)

Anyway, something like this regex *nearly* works:

while ($dn =~ m{
    \s*
    (\d[0-9\.]+|[a-zA-Z][a-zA-Z0-9-]+)                # type
    =
    (\#[a-fA-F0-9]+|                                  # hex value
     "[^"\\]*(?:\\.[^"\\]*)*"|                        # v2 quoted value
     [^\\,;+]*(?:\\[a-zA-Z0-9][a-zA-Z0-9][^\\,;+]*)*) # normal value
    ([,;+]?)                                          # separator
}gx) {
    print "type $1\n";
    print "value $2\n";
    print "separator $3\n";
}

For some reason, this always stops matching before the penultimate RDN, eg
"cn=Chris Ridd,ou=Engineering,o=MessagingDirect,c=CA" prints out the cn and
ou.

Can any regex wizards spot the problem?

Would the equivalent of the $entry->hasValue thing be Net::LDAP's get
method returning undef? I can't remember if this is what Net::LDAP does,
and I don't know what the Mozzilla library does.

Cheers,

Chris
