Raiders created with the summon command can't open doors if they have their NBT data changed with the command. eg /summon raiders:raider ~ ~ ~ {PersistenceRequired:1,faction:2,Owner:Notch}
I compared the data of a raider created with a spawn egg with one created with the summon command, and their data seem to be identical, but the command summoned one can't use doors for some reason.
This seems to apply to all raider mob types.
