Checking passwords with a script
You can implement a script if additional policies need to be used for checking a password that cannot be mapped with the available settings.
Syntax of check scripts
Public Sub CCC_CustomPwdValidate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
With parameters:
policy = password policy object
spwd = password to check
TIP: To use a base object, take the Entity property of the PasswordPolicy class.
Example: Script that checks a password
A password cannot start with ? or ! . The password cannot start with three identical characters. The script checks a given password for validity.
Public Sub CCC_PwdValidate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
Dim pwd = spwd.ToInsecureArray()
If pwd.Length>0
If pwd(0)="?" Or pwd(0)="!"
Throw New Exception(#LD("Password can't start with '?' or '!'")#)
End If
End If
If pwd.Length>2
If pwd(0) = pwd(1) AndAlso pwd(1) = pwd(2)
Throw New Exception(#LD("Invalid character sequence in password")#)
End If
End If
End Sub

Syntax for generating script
Public Sub CCC_PwdGenerate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
With parameters:

Example: Script that generates a password
The script replaces invalid ? and ! characters at the beginning of random passwords with _.
Public Sub CCC_PwdGenerate( policy As VI.DB.Passwords.PasswordPolicy, spwd As System.Security.SecureString)
Dim pwd = spwd.ToInsecureArray()
' replace invalid characters at first position
If pwd.Length>0
If pwd(0)="?" Or pwd(0)="!"
spwd.SetAt(0, CChar("_"))
End If
End If
