Re: krb5_init_context()

Hi Greg, the issue that i am talking about is that krb5_init_context() 
gets its config from the environment var KRB5_CONFIG. We are looking for 
an initialization of the krb5 context that doesn't rely on the 
environment.  I was hoping that was krbt_init_secure_context(). Is there 
some OTHER way of passing the config that is retrieved via KRB5_CONFIG 
in a non environment variable manner?

Thanks, Scot
