[keycloak-user] Kerberos authentication in Windows

[Otaño Pavo, Cesar]

Hi,



I'm trying to set up user authentication mechanism for my website using Keycloak and Kerberos protocol. I have followed instructions from here: http://matthewcasperson.blogspot.com/2015/07/authenticating-via-kerberos-with.html



In Keycloak configuration menu I have changed Authentication Flow for Browser Kerberos from alternative to required. settings<http://i.imgur.com/hgAnHJJ.png>.

But after that when I'm going to my web page I got message "Kerberos is not set up. You cannot login."



Aditional information:



·         Keycloak is installed in Windows Server 2012.



·         Command to create keytabfile:

ktpass -out c:\keycloak.keytab -princ HTTP/facultativoskeycloak.sanbox.local at SANBOX.LOCAL -mapUser Keycloak at SANBOX.LOCAL -pass XXXXX -kvno 0 -ptype KRB5_NT_PRINCIPAL -crypto RC4-HMAC-NT



·         Configuration KRB5.ini located in c:\windows

[domain_realm]

    .sanbox.local = SANBOX.LOCAL

    sanbox.local = SANBOX.LOCAL

[libdefaults]

    default_realm = SANBOX.LOCAL

    permitted_enctypes = aes128-cts aes256-cts arcfour-hmac-md5

    default_tgs_enctypes = aes128-cts aes256-cts arcfour-hmac-md5

    default_tkt_enctypes = aes128-cts aes256-cts arcfour-hmac-md5

[realms]

SANBOX.LOCAL = {

    kdc = sb-ad.sanbox.local

    admin_server = sb-ad.sanbox.local

    default_domain = SANBOX.LOCAL

}



·         Kerberos Integration:



Allow Kerberos authentication:                      YES
Kerberos Realm                                            SANBOX.LOCAL
Server Principal                                             HTTPS/facultativoskeycloak.sanbox.local at SANBOX.LOCAL
KeyTab                                                          C:/keycloak.keytab
Debug                                                            YES
Use Kerberos For Password Authentication YES
