vsql_getpw: failed select

[miral]

Hi all,   I have succesfully installed sqwebmail with vpopmail+mysql. Thanks to Mr.Einar Bordewich  for the workaround solution installing sqwebmail + vpopmail + mysql. But, I still have sqwebmail authentication problem. Initially, after I started authdaemond start, the authentication was working properly. After I relogin again ( the 4th login), the authentication was failed. I got the message vsql_getpw: failed select.   Could anybody give me some hints ??   best regards -miral-
