I've used FBA for my site. Authentication is done using Active Directory.
The login and authentication works perfect but sometimes the login does not work. Then after resetting the same password again, it works well.
For example, the password is:$2014
Initially, it works well. Then after few days passing, it stops working. Then if I manually reset the password to $2014. It again starts working.
I don't know what is the problem. Any suggestion will be appreciated.
