Yet another question

I'm using OTRS in a municipal environment. The customers are being pulled from our Active Directory. Is there some way to let OTRS know which agency they work for? We currently know john.doe is a Health Department child vaccination worker because he's in the Child Services OU which is a child of the Department of Public Health OU. Our "department" field in the AD is all over the place - john.doe's department field may be HD, Health, Health Dept, Health Department, etc. So for now my priority is to run a script to reset department based on OU then map department in OTRS - then figure out someway to run reports based on the department of the customer (if that's even possible).
Is that the best way to do it? Is there some alternative? Thanks!
