Decode SOAPUI password digest

Since I know the password and see the Base64_nonce, created time stamp text, and password digest in the SOAP envelope, shouldn't I be able to recode the digest and get the SOAP envelope digest?

nonce = Decode(base64_Nonce)

Options are:

Password_Digest = Base64 ( SHA-1 (nonce + created + Base64(SHA1(password)) )

or

Password_Digest = Base64 ( SHA-1 (nonce + created + password) )

Neither digest calculation option matches test password digest.

SOAPUI has no issue connecting to test site, my attempts over several days not so much. I'm suspecting an authentication issue in my code.
