Is there an ldap attribute in IdM/IPA that is to be used to describe a role to be used by a automember rule?

Issue

• I am looking for a attribute that can be used to store role information that eventually will enter the IdM system from a external IAM system
• I want to use that information in automember rules
• So far I have seen a departmentNumber and a employeeType from the inetOrgPerson objectclass, but I'd rather use something that is a standard (and perhaps with role in the name of the) attribute
