That's just DEBUG, so nothing to worry about per se (it would be WARN
or ERROR otherwise).

That's good as that means the IDP has properly encoded and sent uid as
an attribute.
To make the attribute available you'll need to literally do what the
message says is missing:

<Attribute name="urn:oid:0.9.2342.19200300.100.1.1" id="uid"/>

The SP told you above.

> SP attribute map file about uid :
> 
> <Attribute name="urn:oid:0.9.2342.19200300.100.1.10" id="uid"/>

That's mapping a different attribute to "uid", one that (a) does not
represent "uid" (but "manager") and more importantly one with a
different OID (note the 0 at the end) which is why the SP said that
urn:oid:0.9.2342.19200300.100.1.1 was unmapped (because it still is).
