See RFC4533 section 2.2 ... mode i.e. refreshOnly or refreshAndPersist.

blindly: I'm not familiar with the Perl module you reference, but perhaps 
you need to be explicitly specifying this value (i.e. perhaps your API has 
you sending some uninitialized, invalid value)?

methodically: packet sniffing, say using wireshark and/or slapd debugging 
facilities, and sit down and figure out if you're sending valid BER/mode 
value/etc. Or if your client API has some debugging options, but again, 
I'm not familiar with that side.
