Any of the normal means for opening an MboSet will work on the ALNDOMAIN object. Here's one example.
from psdi.mbo import SqlFormat
sf = SqlFormat("domainid = 'BOEDIR' and value = :1")
sf.setObject(1, "ALNDOMAIN", "VALUE", "your value that you want to check for")
alnSet = mbo.getMboSet("$findinBOEDIR", "ALNDOMAIN", sf.format())
if alnSet.getMbo(0):
service.log("value found in domain")
else:
service.log("value not found in domain")
