Somehow a new line character is regularly being appended to base64 encoded passwords - trim whitespace from decoded value.

A recent example is 'slavepassword' was encoded as 'c2xhdmVwYXNzd29yZAo=' when actually it should be 'c2xhdmVwYXNzd29yZA=='

(A WARN should also be logged if something has been trimmed)
