We want to create a unique sAMAccountName

[satishNG (Ng Satish Natti Gunta)]

We want to create a unique sAMAccountName using a specific pattern: the first letter of the user’s first name, the first three letters of their last name, followed by three random characters. Could you help with a code snippet to implement this logic?

Hi @satishNG,

You can use cloud rule Account Profile Attribute Generator | SailPoint Developer Community

Find below code:

<Rule language="beanshell" name="Generate Username" type="AttributeGenerator">
  <Description>This will generate a username.</Description>

public String generateUsername ( String firstName,  String lastName) {

  // Data protection.
  firstName = StringUtils.trimToNull( firstName );
  lastName = StringUtils.trimToNull( lastName );
  // Get the first letter of the first name
   String firstLetter = firstName.substring(0, 1).toLowerCase();
    
   // Get the first three letters of the last name
   String firstThreeLettersLastName = lastName.substring(0, Math.min(3, lastName.length())).toLowerCase();
    
   // Generate three random characters
   String randomChars = generateRandomChars(3);
    
   // Combine to form the sAMAccountName
   String sAMAccountName = firstLetter + firstThreeLettersLastName + randomChars;
  
  if ( isUnique ( sAMAccountName ) )
    return sAMAccountName;
  else
   return generateUsername ( firstName,  lastName);
}

private String generateRandomChars(int length) {
    String chars = "abcdefghijklmnopqrstuvwxyz0123456789";
    Random random = new Random();
    StringBuilder sb = new StringBuilder(length);
    
    for (int i = 0; i < length; i++) {
        sb.append(chars.charAt(random.nextInt(chars.length())));
    }
    
    return sb.toString();
}

public boolean isUnique ( String sAMAccountName ) throws GeneralException {
  return !idn.accountExistsByDisplayName(application.getName(), sAMAccountName);
}

return generateUsername( identity.getFirstname(), identity.getLastname());

• Validate the Rule:
• First, convert your rule into XML format.
• Use the IdentityNow Rule Validator tool (available on Compass) to validate the rule locally.
• Ensure the validation result is “Validation: SUCCESS.”
• Prepare Submission Files:
• After successful validation, take a screenshot of the success message.
• Save and include the validated XML file.
• Submit to SailPoint:
• Share both the screenshot and the XML file with your SailPoint team or professional services contact so they can upload the rule to your tenant.
