Applysys account locked

Issue faced :- When applying patch, adpatch was unable to accept apps user password but strangely it was allowing me to login as apps user

Issue Resolution :- Found out that Applsys user accout was locked

select user_name,end_date from applsys.fnd_user where end_date <> null;

update applsys.fnd_user
set end_date = NULL
where user_name = 'APPLSYS';
