Query On NIS

[Vic006]

My query is we have NIS environment with 2300 unix users.We are going to implement password aging.

We are afraid that when multiple users change their password at the same time,can this lead to map corruption?

How the update happens in the map ?Is it one by one(serial) or simultenious ( parallel)?

Shalom,

No, implementing aging on 2300 users at one time will not lead to corruption. The OS has safeguards and queues them up. The system may get a little sluggish at times but it will be handled. It is not a lot of i/o

Is there any document related to this.

Hi,

this document (man-page)
http://docs.hp.com/en/B2355-90692/yppasswdd.1M.html
describes the arguments
-m NOPUSH=1
which I would use in such an environment:
So not each change of the passwd of a user will lead to map-updates in your whole environment.
Do these updates by a crontab entry. Inform your users, that their password-change will not be effective immediately but after a time gap (depending on your crontab setting).
