# When developing a query through a Solicit-Response port you get the error: “An error occurred while parsing EntityName”

This error is caused if you include an ampersand directly in your query string. If you build queries in ADSIEdit they might look like:

`(&(objectCategory=user)(sAMAccountName=Jane))`

The “&” character is not allowed in XML. Instead use “&”

For example:

`<Directives WhereToBind="LDAP://DC2008R2/CN=Users,DC=test,DC=com" SearchScope="onelevel" Filter="(&amp;(objectCategory=user)(sAMAccountName=Jane))" PropertiesToReturn="distinguishedName"/>`
