Kerberos multi domain - Update

[BOUCHER, Flavien]

Hi Tim,

when I try I obtain this result :

java.lang.ClassCastException: java.lang.NegativeArraySizeException incompatible with com.ibm.security.krb5.KrbException
        at com.ibm.security.krb5.g.a(g.java:78)
        at com.ibm.security.krb5.g.a(g.java:10)
        at com.ibm.security.krb5.internal.tools.Kinit.a(Kinit.java:126)
        at com.ibm.security.krb5.internal.tools.Kinit.<init>(Kinit.java:65)
        at com.ibm.security.krb5.internal.tools.Kinit.main(Kinit.java:150)
com.ibm.security.krb5.KrbException, code état : 0
        message : java.lang.ClassCastException: java.lang.NegativeArraySizeException incompatible with com.ibm.security.krb5.KrbException


Is it an issue with my keytab file ?

Regards.
Flavien.

Flavien,

Have you tried:

kinit user_name at MSDEMO2

Thanks,
Tim

Hi,

thaks for your answer Edward. My two KDC have distinct IP @ and port.

I have done a test with KINIT. When I run 'KINIT -A user_name'  , the KINIT command build user_name at MSDEMO<mailto:user_name at MSDEMO>  , MSDEMO is the default_realm setup in my krb5.conf. How could I obtain user_name at MSDEMO2<mailto:user_name at MSDEMO2> except by changing default_realm in krb5.conf ?

Regards.

Flavien.

As far as I know, MIT kerberos can run multiple KDC's from the same machine, but each realm needs to have it's own IP or set of ports.
