Opensis problem installation on shared server?

trying to install open sis on a shared server, it giving me ""This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)"" error , i also tried to set mysql%26gt; SET GLOBAL log_bin_trust_function_creators = 1; it ask for privileges ,also tried manual installation ,but no luck, any suggestions??
