$ cd ~/projects/PAS/Products/PluggableAuthService-trunk/plugins/
$ grep -l prefix *.py
BasePlugin.py
DynamicGroupsPlugin.py
ZODBGroupManager.py
ZODBUserManager.py


Each plugin derived from BasePlugin has a 'prefix' property.  The stock
plugins which generate principal IDs (users or groups) prepend the
prefix to those IDs when returning them to callers.  Before PAS 1.1b1,
those plugins were hardwired to use their own IDs (with an underscore
separateor) as the prefix;  now, the user can change the prefix on a
per-plugin basis.
