Yes, that was a bit odd. Same password, different hash. Even with
verify tool, there was mismatch. So I decided to go for SHA512,
without encryption.
Using user@domain as your ID solved your problem, and this side issue
of which hash scheme you're using is probably irrelevant.
You misunderstand what {SHA512-CRYPT} does compared with {SHA512}. It is
normal to get a different hash with the same password when you regenerate
the hash because a different random salt was chosen (the part between the
'$6$' and the next '$') -- it used as part of the hash computation.
{SHA512} is a straight saltless hash -- the same password maps to the
same hash. This makes it prone to dictionary attacks (i.e. pre-generated
tables of plaintext/hash values).
If you support both schemes, SHA512-CRYPT is much stronger.
