I'm attempting to connect to a database using Kerberos, everything works except for two issues. First, when I execute my code I am asked two enter my password not once but twice. Then my query is sent to my database and results are returned.
The above problem stems from what I belive the root cause, or second issue I'm having is, I JDK's inability to read the keytab.
com.sun.security.jgss.initiate {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
useTicketCache=true
principal="principal@REALM"
useDefaultCcache=true
};
com.sun.security.jgss.accept {
com.sun.security.auth.module.Krb5LoginModule required
ticketCache=true
storeKey=true;
};

****output from mongo****
I understand that I haven't disabled keyboard input but this is because as you see from the output above I'm unable to read the keytab or cache.
Server and Client both have matching krb5.conf, I am able to kinit, ktadd, klist all expect principals with correct enc types.
I even went so far as to chmod 777 the keytab just to make sure this wasn't a permissions issue.
