Possible to set password expiry for ldap authentication?

[Yong Bong Fong <bfyong@xxxxxxxxxxxxxxx>]

Dear friends,

 I have a long running squid + ldap authentication for internet access. 
Now I wish to set it up so that the user password expires after certain 
period and the aged password can no longer be used to access the 
internet. Is it possible?
thanks for taking time reading my message,

Regards
Y
