But problem perssiste and sysadmin cannot connect.

Any help please?

-Is ther any query to verify its account status?

This issue is generic.

Check the password with the following;

select fnd_web_sec.validate_login('SYSADMIN','<password of SYSADMIN>') FROM DUAL;
select fnd_web_sec.validate_login('<other EBS username>',<password of GUEST>') FROM DUAL;
select fnd_web_sec.validate_login('GUEST',<password of GUEST (**1)>') FROM DUAL;

Follow -> All User Can't Login to EBS by "Login failed. Please verify your login information or contact the system administrator" Even If Using a Right Password (Doc ID 2680955.1)
