Using a command-line interface

> dsmod user “<UserDN>” -pwdneverexpires yes

Using VBScript

‘ This code sets a

users password to never expire

‘ —— SCRIPT CONFIGURATION ——

strUserDN = “<UserDN>” ‘ e.g. cn=rallen,ou=Sales,dc=rallencorp,dc=com

‘ —— END CONFIGURATION ——–

intBit = 65536

strAttr = “userAccountControl”

set objUser = GetObject(“LDAP://” & strUserDN)

intBitsOrig = objUser.Get(strAttr)

intBitsCalc = CalcBit(intBitsOrig, intBit, TRUE)

if intBitsOrig <> intBitsCalc then

objUser.Put strAttr, intBitsCalc

objUser.SetInfo

WScript.Echo “Changed ” & strAttr & ” from ” & _

intBitsOrig & ” to ” & intBitsCalc

else

WScript.Echo “Did not need to change ” & strAttr & ” (” & _

intBitsOrig & “)”

end if

Discussion

Setting a user’s password to never expire overrides any password aging policy you’ve defined in the domain. To disable password expiration, you need to set the bit equivalent of 65536 (i.e., 10000000000000000) in the userAccountControl attribute of the target user.
