[PATCH] DSDB schema attributes with no linkID are wrongly set as one way links

Hi,
I have found that schema attributes entries with no linkID are set as
one way links, which I think is wrong.
When loading the schema, the function dsdb_attribute_from_ldb
initialize the linkID field of the dsdb_attribute structure to 0 if
the entry being loaded does not have linkID. Later, the function
dsdb_setup_attribute_shortcuts sets one_way_link to true when the
dsdb_attribute->linkID == 0, which cause all attributes with no linkID
be considered one way links.
I have found here
http://technet.microsoft.com/en-us/library/cc773309(v=ws.10).aspx that
zero is not a valid value for linkID:
A linked pair is identified by the linkID values of two
attributeSchema objects. The linkID of the forward link is an even,
positive, nonzero value, and the linkID of the associated back link is
the value of the forward linkID, incremented by one.
So I think dsdb_attribute->one_way_link has to be set to false when
dsdb_attribute->linkID is 0.
Thanks,
