Member Function Documentation

checkUserPassword()

UserPasswordPolicy::checkUserPassword	(	UserIdentity	$user,
			$password )

Check if a password meets the effective password policy for a User.

Parameters

UserIdentity	$user	whose policy we are checking
string	$password	the password to check

Returns

Status error to indicate the password didn't meet the policy, or fatal to indicate the user shouldn't be allowed to login. The status value will be an array, potentially with the following keys:

• suggestChangeOnLogin: prompt for a password change on login if the password is invalid.

checkUserPasswordForGroups()

UserPasswordPolicy::checkUserPasswordForGroups	(	UserIdentity	$user,
			$password,

This function does not use the DB, so can be used in the installer.

Parameters

string[]	$groups	list of groups to which we assume the user belongs

Returns

Status error to indicate the password didn't meet the policy, or fatal to indicate the user shouldn't be allowed to login. The status value will be an array, potentially with the following keys:

• forceChange: do not allow the user to login without changing the password if invalid.
• suggestChangeOnLogin: prompt for a password change on login if the password is invalid.

getPoliciesForUser()

array the effective policy for $user

maxOfPolicies()

static UserPasswordPolicy::maxOfPolicies ( array $p1, array $p2 )

static

Utility function to get a policy that is the most restrictive of $p1 and $p2.

For simplicity, we setup the policy values so the maximum value is always more restrictive. It is also used recursively to merge settings within the same policy.

Parameters

array	$p1
array	$p2

Returns

array containing the more restrictive values of $p1 and $p2
