Storing passwords using reversible encryption in Active Directory

[i686-linux]

While running through some user accounts in our ADS setup I noticed that one of them is set to "Store password using reversible encryption." This is no good and does not meet the company's security requirements that I work for. My question is if I uncheck this setting will I possibly lose the ability to login as this account anymore?

I doubt it would not allow the user to login.

If anything, it might require you to reset the user's password.

It doesn't do anything other than what it describes, and won't require the user to change his/her password.
