> On IBM java when obtain-kerberos-ticket is set to true user always get
> {code}
> javax.security.auth.login.LoginException: Bad JAAS configuration: credsType and keytab values are not compatible
> {code}
> According to ibm documentation [1] credsType=initiator and useKeytab are really incompatible.
> This constraint can't be avoided once obtain-kerberos-ticket = true, because keytab path is required in model. 
> {code}
>        "path" => {
> 	    "type" => STRING,
> 	    "description" => "The path of the KeyTab to load to obtain the credential.",
> 	    "attribute-group" => "file",
> 	    "expressions-allowed" => true,
> 	    "required" => true,
> 	    "nillable" => false,
> 	    "min-length" => 1L,

> 	    "storage" => "configuration",
> 	    "restart-required" => "resource-services"
> 	},
> {code}
> And keytab is always set into Kerberos login module options
> {code:title=GSSCredentialSecurityFactory.java}
>             if (IS_IBM) {
>                 options.put("noAddress", "true");
>                 options.put("credsType", (isServer && !obtainKerberosTicket) ? "acceptor" : "initiator");
>                 options.put("useKeytab", keyTab.toURI().toURL().toString());
>             }

> I am not setting to blocker just because I am not sure about importance of obtain-kerberos-ticket. See my question JBEAP-9292.
