Description Jeff Layton 2007-06-02 12:30:22 UTC 
The first attempt to do a lookup of an entry against a wildcard entry always
seems to fail. For instance:

# touch /home/jlayton/foo
touch: cannot touch `/home/jlayton/foo': No such file or directory

Every subsequent lookup of this entry will work until autofs is restarted. The
first one always seems to fail.

First, some info:

autofs-5.0.1-9
kernel 2.6.21-1.3194.fc7 (i686 "normal")

auto.master:
/misc   /etc/auto.misc
/net    -hosts
/home   /etc/auto.home --debug

auto.home:
*       -rsize=32768,wsize=32768,noatime                server:/export/home/&

automount entry from nsswitch.conf:

automount:  files

...excerpt from daemon.debug log during autologin attempt with a home directory
mounted via this wildcard entry:

Jun  2 07:35:28 tleilax automount[2030]: handle_packet: type = 3
Jun  2 07:35:28 tleilax automount[2030]: handle_packet_missing_indirect: token
1, name jlayton, request pid 2651
Jun  2 07:35:28 tleilax automount[2030]: lookup_mount: lookup(file): looking up
jlayton
Jun  2 07:35:28 tleilax automount[2030]: lookup_mount: lookup(file): check
indirect map lookup failed
Jun  2 07:35:28 tleilax gdm[2651]: gdm_slave_session_start: Home directory for
jlayton: '/home/jlayton' does not exist!

If I change the auto.home map to have an explicit entry for 'jlayton' then the
first lookup always works. So this seems to be dependent upon wildcard entries.

Mmm .. I didn't see this in testing.

Found it.
Simple programming error.
Have updated devel and F-7.
An update has been submitted for F7, autofs-5.0.1-11.
Can you check it when you get a chance please.
