.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
The
wbinfo
program queries and returns information created and used by the
\fBwinbindd\fR(8)
daemon\&.
.PP
The
\fBwinbindd\fR(8)
daemon must be configured and running for the
wbinfo
program to be able to return information\&.
.SH "OPTIONS"
