.SH NAME
sasl_checkpass \- check a plaintext password
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR   [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>

\fBint\fR \fBsasl_checkpass\fR(\fBsasl_conn_t *\fR\fIconn\fR, \fBconst char *\fR\fIuser\fR, \fBunsigned\fR \fIuserlen\fR,
     \fBconst char *\fR\fIpass\fR, \fBunsigned\fR \fIpasslen\fR);

.SH DESCRIPTION
.sp
.LP
The \fBsasl_checkpass()\fR interface checks a plaintext password. The
\fBsasl_checkpass()\fR interface is used for protocols that had a login method
before SASL, for example, the \fBLOGIN\fR command in IMAP. The password is
checked with the \fBpwcheck_method\fR.
.sp
.LP
The \fBsasl_checkpass()\fR interface is a server interface. You cannot use it
to check passwords from a client.
.sp
.LP
The \fBsasl_checkpass()\fR interface checks the posible repositories until it
succeeds or there are no more repositories. If
\fBsasl_server_userdb_checkpass_t\fR is registered, \fBsasl_checkpass()\fR
tries it first.
.sp
.LP
Use the \fBpwcheck_method\fR SASL option to specify which \fBpwcheck\fR methods
to use.
.sp
.LP
The \fBsasl_checkpass()\fR interface supports the transition of passwords if
the SASL option \fBauto_transition\fR is on.
.sp
.LP
If \fIuser\fR is \fINULL\fR, check is plaintext passwords are enabled.
