Description of problem:

There seams to be a delay when changing to a user whose /home/ directory is mounted with autofs. As a consecuence, the first time I log in with "su - user" the systems says it couldn't cd to the /home/user directory. When I try again the cd succeeds. See actual results.
I don't know if it has anything to do but I disabled selinux, the firewall and iptables. The problem persisted after this.

Version-Release number of selected component (if applicable):
autofs-5.0.1-0.rc2.55

How reproducible:
I am using Rocks+ which is a cluster provisioning system to configure Red Hat.
Every time I install with Rocks+ it  fails, however I think that the problem is in autofs or su commands

Steps to Reproduce:
See actual results. After the first try the /home/* directory will be mounted. To reproduce again, restart the system; or wait to the /home/user directory to be unmounted automatically by autofs. Manually unmounting the folder does not reproduce the issue.
