I am using krb5-1.4.2 and I get the following message from valgrind application to check for possible memory leaks in my application.


My code looks like this:


krb5_keytab keytab = 0;


/* status = krb5_kt_resolve(context, keytab_name, &keytab); */


// These variables are properly initialized: context, my_creds, me, starttime, srbServicePrincipalName, options. Only keytab variable is passed to the api as writeen here.


status = krb5_get_init_creds_keytab(context, &my_creds, me, keytab, starttime, srbServicePrincipalName, &options);


I looked into the code it seems that in some cases the tempstr may not be freed.

Thanks, this has already been fixed and will be in the upcoming krb5-1.4.3 release.
