If you use SetPassword it the same as an admin resetting a user password which probably will bypass checking. you should use change password to enforce your password policy.

Question
ASP.NET ADSI Password complexity requirements
Hello:
I am developing a web page for user password reset. I manage to generate the code to reset the user password by impersonation a domain admin account and using the Invoke("SetPassword", "password.123") but I need to check if the new password meets the pasword complexity requirements defined in Active directory policies.
Does any one can help me giving me an example code to check this or maybe the Invoke method used to check this?
This is an urgent request cos my boss is pushing me to finish this site so I am giving 500 points!!!!!!!!
thanks in advance

TMWSIY is right, there is no method of enforcing password security without running the text against the password prior to changing it, the simplest way is to test for [a-z][A-Z][0-9], run each reg expression test by itself for simplicity of reading and modifying (Yes I am very aware that you can do it in one regex test, I am also painfully aware that modifications to such regex can be extremely difficult)
Kavar,
I think your partially right. If you use the usr.Invoke("SetPassword", "password.123") then you must be a domin admin. This works because Pollin is impersonating a domain admin. However, if Pollin uses usr.Invoke("ChangePassword
I _think_ this is how it works but I have not tested it.
Hey guys
you are amazing. Didn't know that I would receive an answer so quickly.
I will use the change password method.
Thanks Kar for your contribution.
Thanks TMWSIY for the exmaples, here are your 500 points.

You could manually check the password using regex to determine if it meets the password policy, but if your password policy changed you would have to modify your code. This is not an ideal solution but maybe a quick fix.
