Hi Experts,
While Iam creating the user,Iam trying to validate the password as per password policy configured in cdb. Please provide suggestions for user password validation as per pwd policy

Example:

leaf password {
  type string {
    pattern ".*[0-9]+.*"; // at least one digit
    pattern ".*[a-z]+.*"; // at least one lower case alpha
    pattern ".*[A-Z]+.*"; // at least one upper case alpha
    pattern ".*[<>~;:!@#/$%^&*=-]+.*"; // at least one symbol (add more symbols)
    pattern ".* .*" { // no spaces
      modifier invert-match;
    }
    length 8..max;
  }
}
