Actually, I didn't use --authuser with imapsync. What I did I changed Internet passwords for all Lotus accounts, but Lotus authentication with ID file was still intract. Because everyone used only Lotus native client, nobody was affected by Internet password change. Then I used imapsync to migrate all account content.
Working imapsync command was quite elaborated, last version looked like: # /usr/bin/imapsync --allowsizemismatch --timeout 60 --host1 source_host --user1 user --password1 source_password --host2 destination_host --user2 user --password2 destination_password --noauthmd5 --buffersize buffersize --nosyncacls --subscribe_all --syncinternaldates --regextrans2 's/Inbox/INBOX/' --regextrans2 's,\\,/,g' --regextrans2 's,//,++,g' --skipheader '^X-|^Received|^Content-|^Subject|^References|^Mime|^Cc' --fast --skipsize
