> We need a configurable mapping from full user names (eg. [email protected])
> to local user names (eg. omalley). For many organizations it is sufficient to
> just use the prefix, however, in the case of shared clusters there may be
> duplicated prefixes. A configurable mapping will let administrators resolve
> the issue.
