In limit_krb5_enctypes(), if I did not give gss_set_allowable_enctypes()
the list of enctypes in an increasing order, creating the krb5 context for  
root would fail. When gave them in order root got its context... 

I figured it was some type of krb5 lib quirk, since the default enctypes 
are also in increasing order... 

steved.
