NIS and automounter...
Have an AIX 5.2 box. I had automounter already setup to control /home using /etc/auto_home as an indirect automount map.
Then we added NIS. We have it working, but for some reason, the NIS table auto.home seems to override /etc/auto_home entries. Of course, there are some duplicates (usernames that appear in NIS and /etc/passwd, with different home directories and UIDs, etc.). I want /etc/auto_home to override NIS. I need to synch up UIDs, home directories (in most cases, but there are some exceptions), etc. but I was hoping to be able to add some select users from NIS while I go about the long process of syching up users and UIDs.
I'm used to Solaris where I have an /etc/nsswitch.conf file and I can specify the order to search. Is there anything I can do to configure the order that the automounter will use (i.e. so I can say "use /etc/auto_home before you go to NIS", etc.)?

auto.master
AUTO.MASTER(5) File Formats Manual AUTO.MASTER(5)
NAME
/etc/auto.master - Master Map for automounter
DESCRIPTION
The auto.master map is consulted when the autofs(8) script is invoked to set up the necessary mount points for the automounter. Each line
in this file describes a mount point and points to another file describing the file systems to be mounted under this mountpoint. The access
to those maps is governed by a key.
Access to an automounted file system is customarily done using the path scheme:
/mountpoint/key/path/file,
where the mountpoint will be listed in the auto.master configuration file. The key is matched in the map file pointed to by the master map
(See autofs(5)). The path and the file are referring to the file on the file system mounted.
FORMAT
The file has three fields separated by an arbitrary number of blanks or tabs. Lines beginning with # are comments. The first field is the
mount point. Second field is the map file to be consulted for this mount-point. This field is of the form maptype:mapname, where maptype
is one of the supported map types (file, program, yp, nisplus, hesiod, userdir, ldap), and mapname is the name of the map. The third field
is optional and can contain options to+ be applied to all entries in the map. Options are cumulative, which is a difference from the behav-
ior of the SunOS automounter.
The format of the map file and the options are described in autofs(5).
EXAMPLE
/home /etc/auto.home
/misc /etc/auto.misc
/mnt yp:mnt.map
This will generate three mountpoints /home, /misc, and /mnt. All accesses to /home will lead to the consultation of the map in
/etc/auto.home, all accesses to /misc will consult the map in /etc/auto.misc, and all accesses to /mnt will consult the NIS map mnt.map.
