I am running into an issue here, I using autofs with ldap to mount /home 
directories. This is my os version Description: Ubuntu 10.10 Release: 10.10
my /etc/auto.master is commented out.
in /etc/nsswitch.conf last line is
automount: ldap
I can automount my home directory from the NFS server using LDAP with 
out an issue. But after a few minutes of inactivity, when i  try to 
login to the machine and run my application it hangs. My application 
tries to read /etc/config.txt but rather than reading /etc/config.txt it 
tries to mount /home/etc/config.txt , i can see that in the syslog which 
is attached below.
If i were to login and move to another location besides /home/*, the 
command will run fine for example if I cd from/home to any other part of 
the file system like /tmp or /var/log.
