First I have to tell you that the DHCP (and also DNS) servers are not
maintained since years, I not even can find any server-side integration
test that tests the functionality. So very likely those won't work at
all or include major bugs. Help to test, fix, and document is however
appreciated :)

I just tried to add a "dhcpOption" value with Studio. As this attribute
is of syntax octet string the Hex Editor opens. I then choosed the "Edit
as Text" option. The resulting binary is a proper UTF-8 encoded value.
But when saving that there is an error on server side, I think that is a
bug in the LDAP API.

dhcpOption: 0x62 0x72 0x6F 0x61 0x64 0x63 0x61 0x73 0x74 0x20 0x31 0x39
0x32 0x2E 0x31 0x36
