I need information about set password option "max & min time or warning Time ".

Hi,

I think you trying to set the system security policy if so , it is possible only in a tarusted system.

But trusted system will not work with NIS but works with NIS+.

Hi

I dont think NIS supports the standard passwd options for min and max time ( -n -x ). You will have to update to NIS+ to achieve this.

good luck

You can setup password aging with NIS, but the min and max time can only set in weeks, and there is no warning time.

For example:

user:password,MmNN:uid:gid:gecos:path:shell
M=max (.=0,/=1,0=2,9=11,A=12,Z=37,a=38,z=63)
n=min
NN=time password was changed last time

man 4 passwd

should give you enough information to build it, but a warning mechanism has to be implemented manually by yourself.

And not all vendors accept this style of password aging.
e.g. Solaris(sun) works fine, but IRIX(sgi) ignores is completely.
