[xwiki-users] How to set the max unsuccessful login attempts to some numbaer say 4?

I had put this question earlier too but knowing that its not configurable in xwiki as of now as OOB feature. So started implementing this feature myself with some modification in code. I did modifications in checkPassword method of XWikiAuthServiceImpl. Basically i want to put the *passwordLockCount *as name and *1* as value in xwikiintegers table(when user tries any unsuccessful login attempt). For this i used the api i.e userObject.setIntValue("passwordLockCount", 1) where userObject is of type BaseObject. But it does not put the value in xwikiintegers table rather it put in cache. Please recommend me the right API the to put this number property in xwikiintegers table? *i also tried * NumberProperty passwordLockCount = new IntegerProperty(); passwordLockCount.setName("passwordLockCount"); passwordLockCount.setValue(1); userObject.addField("passwordLockCount", passwordLockCount); But it also does not put the property in database?
