The equivalent (or near alternative) of com.ibm.websphere.tivoli.* for openliberty with java 17

As the title says, do you have:

1. Suggestions
2. Alternatives
3. An or have encountered this case that you have migrated to openliberty from websphere server? Thank you!

I have resorted to ldap of openliberty.

UPDATE

Thank you for bringing this up @Doug Breaux, as I was into updating my code, I forgot to update this post.

Moving on, what I did is a of combination of unboundid and vanilla Java LDAP to succeed in converting my methods. But, I plan to migrate it all in unboundid as I see it, it is being supported fairly good continuously.

Porting my code. Here is the list of PDUser https://www.ibm.com/docs/en/sva/10.0.7?topic=groups-administering-user-information methods that I have primarily used.

But since I will no longer use Websphere, I am now using Java LDAP Vanilla code like:

    String ldapUrl = "";
    String searchBase = "";
    String searchFilter = "cn="+userName;
    String username = "";
    String password = "";

    Hashtable<String, String> env = new Hashtable<>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, ldapUrl);
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, username);
    env.put(Context.SECURITY_CREDENTIALS, password);
    DirContext ctx = null;
    try {
        ctx = new InitialDirContext(env);
        SearchControls searchControls = new SearchControls();
        searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);

        NamingEnumeration<SearchResult> results = ctx.search(searchBase, searchFilter, searchControls);

        if (results.hasMore()) {
            SearchResult result = results.next();
            return true;
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        ctx.close();
    }

For unboundid java code, I have read through this https://docs.ldap.com/ldap-sdk/docs/getting-started/controls.html
