Based on some simple experimentation I added the following to my /etc/auto_master file: /nxx/etc/auto.nxx Added a /etc/auto.nxx file containing [[[ #!/bin/sh exit 1 ]]] Made /etc/auto.nxx executable and ran `automount -vc` to activate it. Then I ran this: $ ls -l /nxx/x ls: /nxx/x: Input/output error Changing the exit code to 0 in /etc/auto.nxx I then repeated the ls command and got: $ ls -l /nxx/x ls: /nxx/x: No such file or directory So it seems to me that unless the commands to query LDAP fail that your script should exit with zero exit code and no output to indicate there is no such mount point. So like I said before it seems to me that this is a bug in your /etc/auto.spi Changing 'exit 1' to 'exit 0' and having the script send nothing to stdout gets it to work. Thanks for taking the time to track this down. Blair
