commit ce7c418ca4f8f82e61a9a02a6589ab1c4df51d63

python/samba/tests: fix samba.tests.auth_log_pass_change for later gnutls
later gnutls that support GNUTLS_PBKDF2 currently fail,
we need to conditionally switch test data to reflect use of
'samr_ChangePasswordUser3' or 'samr_ChangePasswordUser4'
depending on whether GNUTLS_PBKDF2 is supported or not

s4/rpc_server/sambr: don't mutate the return of samdb_set_password_aes
prior to this commit return of samdb_set_password_aes was set to
NT_STATUS_WRONG_PASSWORD on failure. Useful status that should be
returned such as NT_STATUS_PASSWORD_RESTRICTION are swallowed here
otherwise (and in this case can be partially responsible for failures
in test samba.tests.auth_log_pass_change (with later gnutls)
