O.S. - HP-UX

Solution:
To implement the solution, please execute the following steps:

Disable the trigger 'ALR_FND_USER_UAR' using sqlplus :

- SQL> alter trigger ALR_FND_USER_UAR disable;

- Retest Login.


Metalink suggest the following doc id's solution:
1) Note:388695.1
2) Note:357998.1
And Bouncing the Apache could resolve the error in some cases.
