OIM 11gR2-[Security:090302]Authentication Failed

Hi All,

We have configured an OIM 11gR2 environment and we are facing an issue regarding OIM Authentication. When an user is created we can authenticate to the web console with the user OIM, several hours after we can't authenticate again with the same user and the message "Invalid sign in." is showed while the file log show something like the following:

javax.security.auth.login.FailedLoginException: [Security:090302]Authentication Failed: User usuarioTest denied

When the problem happens we can authenticate with xelsysadm and search the user account, we can see that the account status is Unlocked and the identity status is Active. if we lock and unlock the account that has authentication Failed, the problem si resolved.
