    • setKeyTabLocation

      public void setKeyTabLocation(org.springframework.core.io.Resource keyTabLocation)

      The location of the keytab. You can use the normale Spring Resource prefixes like file: or classpath:, but as the file is later on read by JAAS, we cannot guarantee that classpath works in every environment, esp. not in Java EE application servers. You should use file: there. This file also needs special protection, which is another reason to not include it in the classpath but rather use file:/etc/http.keytab for example.

      Parameters:
      keyTabLocation - The location where the keytab resides

    • setDebug

      public void setDebug(boolean debug)

      public void setHoldOnToGSSContext(boolean holdOnToGSSContext)
      Determines whether to hold on to the GSS security context or otherwise dispose of it immediately (the default behaviour).

      Holding on to the GSS context allows decrypt and encrypt operations for subsequent interactions with the principal.

      Parameters:
      holdOnToGSSContext - true if should hold on to context
