This configuration would be using IEEE 802.1X and LEAP with WEP keys and
looks fine for that kind of use.

This looks like the AP would indeed be advertising WPA support. Since
your configuration file did not limit the cipher suite, I would assume
that the AP is trying to use one of the Cisco specific ciphers (CKIP,
CMIC, or CKIP+CMIC). It _may_ also allow non-WPA case (i.e., your
earlier configuration with IEEE 802.1X). It would be worth verifying
whether this is indeed allowed before spending much time with this.

No, those are not used with LEAP.
