rc4 ldap backend groupmap bug?

[godfrey]

When trying to add a groupmap entry for a unix group that already has a 
groupmap entry I get the following
error "ldapsam_add_group_mapping_entry: Group 3 already exists in LDAP"

I can reproduce this with rc1 to rc4

It does not happen if use tdb backend, is ldap backend supposed to be 
different?

I am running mandrake samba3 packages thus net3 instead of net.

John H Terpstra in an email to samba list said *

"Not quite! You can not have more than one NT Domain Group per UNIX Group.
But you can have more than on NT Local Group per UNIX group.

Try:

net groupmap add ntgroup="Flying Pigs" unixgroup=sys type=l"

see http://lists.samba.org/pipermail/samba/2003-September/000074.html

so I assume ldap behaviour is wrong.
