[midPoint] Set maximum character limit for username + iteration

[Macias, Daniel]

Hello,

I trying to set a maximum amount of characters for the username in AD to 8 due to the limitations of other apps that use the same attribute value. When constructing the username in the Object Template from CSV feed using First Name, Last Name, and, if available, Middle Name, I have the following mapping;

<mapping>
        <name>Generate Login Name from CSV</name>
        <source>
            <c:path>$focus/givenName</c:path>
        </source>
        <source>
            <c:path>$focus/familyName</c:path>
        </source>
        <source>
            <c:path>$focus/additionalName</c:path>
        </source>
        <expression>
<script xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:c="http://midpoint.evolveum.com/xml/ns/public/common/common-3"xsi:type="c:ScriptExpressionEvaluatorType">
                <language>http://midpoint.evolveum.com/xml/ns/public/expression/language#Groovy</language>
                <code>
                     def givenNameStr = ''+givenName
                     def familyNameStr = ''+familyName
                     def additionalNameStr = ''+additionalName

                     if (iteration == 0 & additionalName != null) {
                     return (givenNameStr.substring(0,1) + '' + additionalNameStr.substring(0,1) + '' + familyNameStr.substring(0, Math.min(familyNameStr.length(),5))) + iterationToken;
                       }
                     else if (iteration == 0 & additionalName == null) {
                        return (givenNameStr.substring(0,1) + '' + givenNameStr.substring(0,1) + '' + familyNameStr.substring(0, Math.min(familyNameStr.length(),5))) + iterationToken;

                     }
                     else if (iteration > 10 & familyNameStr.length() > 5 & additionalName == null) {
                     return (givenNameStr.substring(0,1) + '' + givenNameStr.substring(0,1) + '' + familyNameStr.substring(0, Math.min(familyNameStr.length(),4))) + iterationToken;
                     }
                     else if (iteration > 10 & familyNameStr.length() > 5 & additionalName == null) {
                     return (givenNameStr.substring(0,1) + '' + givenNameStr.substring(0,1) + '' + familyNameStr.substring(0, 4)) + iterationToken;
                     }

                     else {
                     return "";
                     }
                </code>
            </script>
        </expression>
        <target>
            <c:path>$focus/extension/ccxLoginName</c:path>
        </target>
    </mapping>

In other words, I'm using the first name initial + the middle name initial (if available, if not, then the first name initial will be used) + the first 6 letters of the last name (if it has more than 6 characters) +  iteration; when there's no iteration, the username will not have a number at the end.

But when the iteration reaches the 10th iteration, I'd like to cut down the last name to a max of 5 characters so the username will have a total of 8 characters.

The mapping above is working but it ignores the max, is simply ignored. The username is created with 6 characters + iteration. For example, John J. Johnson, if username value already exists 10 times, the should be constructed as JJohns10, instead I'm getting JJohnso10.

Any ideas how to accomplish this?

Thanks in advance,

Daniel
