Another option is [OpenPBS](http://www.openpbs.org/) and [Password Storage and Retrieval](http://www.lam-mpi.org/software/psr/) (PSR), where you encrypt your AFS password with a public key and put it in your home directory, and trusted machine(s) which have the private key on local disk then decrypt your password and run your job. MIT uses a variant of this (e.g. [a](http://web.mit.edu/longjobs/www/) & [b](http://mit.edu/longjobs-dev/notebook/)) that uses their own code (see [longjobs documentation](http://web.mit.edu/longjobs-dev/doc/netsec.txt) sections III and IV) instead of PSR.
- [[RedHat]] Linux: ([src](https://lists.openafs.org/pipermail/openafs-info/2002-July/005085.html)) change the last line of /etc/sysconfig/afs to `AFS_POST_INIT="/usr/bin/fs setcrypt on"`
- Windows ([src](https://lists.openafs.org/pipermail/openafs-info/2003-June/009416.html)) set the following registry value named `SecurityLevel` under `HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters` to 2.
