 After installing a libpam built with DEBUG defined and passing the
 `debug' option to pam_krb5.so, logging in using login(1) results in
 [1]this log, and using xdm(1) in [2]this log. After adding some
 [3]additional printfs to pam_krb5.so, the logs look like [4]this for
 login(1) and like [5]this for xdm(1).
 
 I don't understand why the chown(2) in pam_sm_setcred() (pam_krb5.c
 rev. 1.21, line 565) fails if run by xdm(1).
