Do they support authentication with LDAP? If so, you can configure your LDAP server to use SASL to check the user passwords against Kerberos. See this article: http://thomas.dereyck.eu/wiki/Setting%20up%20an%20LDAP%20server#Enabling_pass-through_authentication_to_Kerberos

I wonder if I can decrypt
the password from Kerberos server manually to have it in a plaintext,

As Chris said, that's a big security risk and completely defeats Kerberos' purpose. If the applications don't allow any external authentication, you might be able to find a plug-in that sits between the application and the DB that intercepts the auth requests and services them with SASL or Kerberos directly.
