How to fill in a full name from one BP attribute in Bitrix?

Question

LDAP

Good afternoon.

I am setting up Bitrix integration with ldap. The ldap module assumes that First Name Last Name and Middle Name are separate attributes. In my case, they are stored in one attribute in AD.

Is it possible to somehow fill all 3 fields from one attribute?
Type
displayName = Ivanov Ivan Ivanovich
Surname - displayName[1] First
name - displayName[2]
Middle name - displayName[3]
