In the manual page for "mangled names" parameter, the detail of "hash" algorithm is described following "If mangling is used then the mangling algorithm is as follows:" .
This should be moved to "mangling method".
Still not fixed yet at Samba 3.2.4.
Fixed with commit d1ad143a in master.
Will be included in 3.4.4.
Closing out bug report.
Thanks for reporting!
