R6 LDAP With Avaya IP Office Telephones

I am using an Avaya IP Office Telephone Switch, which has the facility to look up using LDAP, the domino directory.

Unfortunately, the standard query in the phone switch config is designed to work with MS Active Dir:

telephoneNumber,otherTelephone,homePhone=H,otherHomePhone=H,mobile=M,otherMobile=M

Has anyone got one/offer advice on getting it to lookup the information?? It seems they changed LDAP from R5 to R6.

Thanks,

Matt.
