The difference w.r.t. krb5p is t= hat it does not encrypt the NFS payload. I doubt it will make any difference, but it sounds like you'll know soon enough. I now have a hunch w.r.t. what might be broken, but I need to look at the c= ode (and if my hunch seems correct) and maybe come up with a patch. You could try the "syskrb5" mount option, which avoids use of the keytab and allows "system operations that maintain the state" to use AUTH_SYS, while t= he rest (all involving file data) use Kerberos. (If my hunch is correct, this will not fix the problem, but might cause it to behave better.) rick ps: I accidentally did this as an email reply... --=20 You are receiving this mail because: You are the assignee for the bug.=
