Q:

Add atribute to a existing user in LDAP with JAVA

i'm trying to modify a existing user and add a attribute to him. I'm using the following code:
Attributes attrs1 = new BasicAttributes(true);
attrs1.put("proxyHash", generateProxyHash(account, "123456"));
ldapContext.modifyAttributes(username, DirContext.ADD_ATTRIBUTE,attrs1);

But i've received an exception that says 'the attribute proxyHash is not allowed'

A:

Joao Carlos found solution himself:
The user I was trying to change was in a different schema, this schema haven't the attribute specified. After this fix the code works.
