Hello Jaime,

which strongSwan version are you using? There was a bug concerning
the ASN.1 encoding of the Email RDN (E=) in right|leftid introduced
with version 4.2.15 which was fixed with version 4.3.4. This bug
causes the comparison between the ID defined by rightid and the subject
DN defined by the certificate to fail. The debian lenny distribution
originally had version 4.2.4 but there have been backports to newer
versions later on.
