ContextSource pool problem when using DirSync

java 1.8
spring boot: 2.0.3.RELEASE
spring-ldap-core: 2.3.2.RELEASE

When I use DirSync cookie for control response in one request,
it seems that all other requests called using this ContextSource start using DirSync

test:

public void callQueryAfterDirsync() {
    DirSyncContextProcesor proc = new DirSyncContextProcesor(null);
    getByDirsync(proc);
    SearchControls controls = new SearchControls();
    controls.setTimeLimit(0);
    controls.setCountLimit(0);
    controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
    String [] attr =  {"memberOf"};
    controls.setReturningAttributes(attr);
    List<LdapUser> result = template.search("", "cn=myUser", controls,  userContextMapper);
    System.out.println(result.get(0).getDnAdGroups().toString());
}
    
public List<LdapUser> getByDirsync(DirContextProcessor proc) {
    SearchControls controls = new SearchControls();
    controls.setTimeLimit(0);
    controls.setCountLimit(0);
    controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
    return template.search("", "objectClass=user", controls, userContextMapper, proc);
}

If I call normal search after dirSync search I cannot get memberOf attribute any more

Start by running the provided Java reproduction with Spring LDAP 2.3.2 and compare a normal search before and after getByDirsync. Inspect the ContextSource pooling behavior and DirSyncContextProcesor interaction; done means a normal search after a DirSync search still returns the memberOf attribute.
