never had that problem with apple devices. plese clarify what device are you using to conect:
mac (if soo what version 10.4 tiger - ligon?), ipda, ipod...)
what exactl does your hfs machine see in the log (as it logs if the password is correct or enterend corectly further more is you hfs on a windows machine?...
To help you debug more, you should probaly edit what is being loged ie:
menu > log ? log what >conections...
again i ahve not had nor seen that isues when i have use apple devices with my hfs server. so there is either an isues with your hfs templat/ login credentials/ program you use to connect (try chrome/firefox/opera as it is avialbe for apple device just to test as, if you think it is sarfai!) agin not enougth info to help and shoting in the dark to help lolz good luck...
