S4 Sync Error because of too long DKIM record


UCS to S4 Sync is not working for a specific DKIM entry. As Problem: DKIM-TXT-Records are to long for samba or bind9 and as well the logfile states, the entry is too long.

My problem now is, that I have no idea how to add that entry correctly to the ldap. Where do I have to put the double quotes exactly?

I tried

"v=DKIM1; k=rsa; p=<key_part_1>" "<key_part_2>"


But with that, the error still stays the same. Do I have to split that in multiple TXT entries?
