Possibly. Could you issue a pull with the updates you have in mind to the docs?

Subject:  Re: [cas-user] CAS 5.0.0 SPNEGO issue  

Today, it works a little better : I get 401, my browser send its  
ticket... but no authentication :  

Caused by: KrbException: Invalid argument (400) - Cannot find key of  
appropriate type to decrypt AP REP - RC4 with HMAC  

I have to declare my keytab as default keytab in /etc/krb5.conf to get  
authenticated (keytab is read *before* login.conf) ! It was not  
necessary with CASv3.5.  

If my keytab is not declared in /etc/krb5.conf, login.conf is not read  
either, why ??  

Last test, with only a few parameters :  

cas.authn.spnego.kerberosConf=/etc/krb5.conf  
cas.authn.spnego.mixedModeAuthentication=false  
cas.authn.spnego.jcifsServicePrincipal=HTTP/[email protected]  
cas.authn.spnego.ntlmAllowed=false  
cas.authn.spnego.hostNamePatternString=.+  
cas.authn.spnego.supportedBrowsers=MSIE,Firefox,AppleWebKit  
cas.authn.spnego.hostNameClientActionStrategy=hostnameSpnegoClientAction  
cas.authn.spnego.ipsToCheckPattern=172.+  
cas.authn.spnego.send401OnAuthenticationFailure=false  
cas.authn.spnego.principalWithDomainName=false  

it works...  

Is the documentation needing update ?  

Regards.
