Use of '&' in LDAP filters

[#1]

I would like to perform a complex filter within my LDAP policy, which uses the 'AND' construct. The filter I want to perform is this:

(&(objectClass=person)(objectClass=user))

But when I try to use this in my policy, I get this error:

Error creating object

Bundle is invalid. The entity name must immediately follow the '&' in the entity reference.

I have tried the '&' as-is, and escaped (& amp;), but neither works:

<SearchQuery>(&(objectClass=person)(objectClass=user))</SearchQuery>

<SearchQuery>(& amp;(objectClass=person)(objectClass=user))</SearchQuery>

(Note: I don't really have a space between the & and amp; in my code, but I had to put that there to make it visible on this page.)

Suggestions?
