DESCRIPTION:
The -A account string that was valid when a job
was dispatched can be falsified by using qalter -A
during job run time. Changing the account string
during job run time may only have an impact on the
accounting records of subsequent runs of this job
(after rescheduling/migration).

WORKAROUND:
none

SUGGESTED FIX:
Currently when the accounting record is written in
qmaster the account string is taken from the
current job. This information is changed by
qalter. When starting a job the account string at
dispatch time is already transfered
to execd/shepherd. If it were also tranfered back
to qmaster after job finish and if that account
string were used it were not possible to falsify
this using qalter.

Changed the subcomponent.
