SBM 2009: Authentication via "NT Challenge Response" and SSO

Question posted 11/23/09 by CLS

Hi, using SBM 2009 R1.2 I want to use authetication NT Challenge Response which ist not supported with SSO. I choosed SSO during installation.
Do I have to disable now SSO like described in the Mashup Adminitrator Guide plus Solution S136917 and Defect D8057? Or is it enough to uncheck SSO in the Administrator settings?
