+.SH REBINDING
+.LP
+The
+.B ldap_set_rebind_proc
+function() sets the process to use for binding when an operation returns a
+referral. This function is used when an application needs to bind to another server
+in order to follow a referral or search continuation reference.
+.LP
+The function takes \fIld\fP, the \fIrebind\fP function, and the \fIparams\fP,
+the arbitrary data like state information which the client might need to properly rebind.
+The LDAP_OPT_REFERRALS option in the \fIld\fP must be set to ON for the libraries
+to use the rebind function. Use the
+.BR ldap_set_option
+function to set the value.
+.LP
+The rebind function has the following syntax.
+.B int rebind_function (LDAP *ld, const char *url,int request,ber_int_t   msgid);
+.LP
+The \fIld\fP parameter must be used by the application when binding to the
+referred server if the application wants the libraries to follow the referral.
+.LP
+The \fIurl\fP parameter points to the URL referral string received from the LDAP server.
+The LDAP application can use the 
+.BR ldap_url_parse()
+.LP
+The \fIrequest\fP parameter specifies the request operation that generated the referral. 
+function to parse the string into its components.
+.LP
+The \fImsgid\fP parameter specifies the message ID of the request generating the referral.
+.LP
+The LDAP libraries set all the parameters when they call the rebind function. The application
+should not attempt to free either the ld or the url structures in the rebind function.
+.LP
+The application must supply to the rebind function the required authentication information such as,
+user name, password, and certificates. The rebind function must use a synchronous bind method.

 .SH ERRORS
 Asynchronous routines will return -1 in case of error, setting the
 \fIld_errno\fP parameter of the \fIld\fP structure.  Synchronous
 routines return whatever \fIld_errno\fP is set to.  See
 .BR ldap_error (3)
 for more information.
+.SH NOTES
+If an anonymous bind is sufficient for the application,the rebind process
+need not be provided. The LDAP libraries with the LDAP_OPT_REFERRALS option
+set to ON (default value) will automatically follow referrals using an anonymous bind.
+.LP
+If the application needs stronger authentication than an anonymous bind,
+you need to provide a rebind process for that authentication method.
+The bind method must be synchronous.
