[Robie Basak]

Thank you for your report.

Please can you run "apport-collect 1084178" on the affected machine
(hostb in your example) which will automatically attach relevant
information such as version numbers to this bug?

Also, please attach all relevant configuration files, such as
/etc/autofs.master and /etc/fstab.

Once done, please change the bug status back to New.

Thanks!

** Changed in: autofs (Ubuntu)

Title:
  auto.net does not handle mutliple mount points from a remote

Status in “autofs” package in Ubuntu:
  Incomplete

Bug description:
  When using auto.net and mounting multiple remote exports, only one mount works and autofs steps onto the other mounts.
  The problem appears in /proc/mounts (see details in walk-thru below)
