Java LDAP - Add group to user issue - Error code 53 - WILL_NOT_PERFORM [duplicate]

Answer 1

The solution code is:

BasicAttribute member = new BasicAttribute("member",entryDN);
Attributes atts = new BasicAttributes();
atts.put(member);
ctx.modifyAttributes("GROUP_DN", LdapContext.ADD_ATTRIBUTE, atts);
