My suspicion is that both mechanisms trash each others idea of the
authentication realm, but that is not very deeply founded.

Any idea what to try or look at next ?

1. Compile jabberd with debugging, then run c2s -D and look for signs of
the problem.

2. Look at the decoded SASL exchange (you may find it in debug messages)
for incompatibilities.

Ok, I logged an attempt with GSSAPI only and one with GSSAPI + Digest- MD5 enabled.

In the GSSAPI only case, Adium uses GSSAPI only which succeeds.

In the second case, Adium first tries to authenticate using Digest- MD5 and as it has no password, this first attempt fails. It then tries GSSAPI immediately without reseting the connection, but terminates the connection the first challenge.

When I compare the successful GSSAPI attempt with the failing one, both look quite similar except that in the failing case the first challenge is 272 instead of 276 Bytes.
