AIX UID allocation

I would like to start my AIX UID allocation at a number far above the standard something like say 1000

however for the life of me i can't seem to find a place where i am able to set or see where aix looks for the user id's by default for allocation

common sense would say that it looks in /etc/passwd but if that is the case then i can't seem to figure out how to trick it into using a larger number.

Some of the systems that i will be deploying will have in upwards of 800 users on them and it will make my on-site support people's lifes much more difficult if they have to remember to increment each person in SMIT when they create them

any ideas

found it!

The directory /etc/security contains many files used to configure individual user or system-wide security defaults. The files listed below can be modified to enhance system security at your site:

/etc/security.ids

Holds the value for the next assignment to a group/user id and group/user admin id. Used by mkuser and mkgroup commands.

Sample contents: 4 203 12 200

    where...

    * 4 = administrative user id \(mkuser -a\)
    * 203 = user id \(mkuser\)
    * 12 =  administrative group id \(mkgroup -a\)
    * 200 = group id \(mkgroup
