There is a new setting, which I did not know about:

	leftid=%fromcert

I'm strongly leaning towards undoing the code that causes this to be
neccessary, unless someone can convince me that the default when
using leftcert= should be ID_IPV4_ADDR instead of ID_DER_ASN1_DN. I
can come up with no valid reason for this.

The comment with that commit says:

commit f789468cee4e8d68645eae87d0a016edba575e45
Author: Michael Richardson <mcr at xelerance.com>

    permit leftid= to be used even when using leftcert. Do not override
    the ID type unless the ID type is none, or %fromcert.
    
So it looks like specifying leftid="something" was ignored when leftcert=
was used. However, the fix for this caused a side effect changing the
*default* type of id when leftcert= is used from ID_DER_ASN1_DN to
ID_IPV4_ADDR. This will cause major headaches for people upgrading from
openswan 2.4.x

Thanks. We now know where this is done, and will see about avoiding these in the future.

Let us know how things progres.
