.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Net::LDAP::Control::ProxyAuth\*(C'\fR provides an interface for the creation and manipulation
of objects that represent the \f(CW\*(C`Proxy Authorization Control\*(C'\fR as described by \s-1RFC\s0 4370.
.PP
It allows a client to be bound to an \s-1LDAP\s0 server with its own identity, but to perform
operations on behalf of another user, the \f(CW\*(C`authzID\*(C'\fR.
.PP
With the exception of any extension that causes a change in authentication,
authorization or data confidentiality, a single \f(CW\*(C`Proxy Authorization Control\*(C'\fR
may be included in any search, compare, modify, add, delete, or moddn or
extended operation.
.PP
As required by the \s-1RFC\s0, the criticality of this control is automatically set to
\&\s-1TRUE\s0 in order to protect clients from submitting requests with other identities
that they intend to.
.SH "CONSTRUCTOR ARGUMENTS"
.IX Header "CONSTRUCTOR ARGUMENTS"
In addition to the constructor arguments described in
Net::LDAP::Control the following are provided.
.IP "authzID" 4
.IX Item "authzID"
The authzID that is required. This is the identity we are requesting operations to use.
.IP "proxyDN" 4
.IX Item "proxyDN"
In early versions of the drafts to \s-1RFC\s0 4370, draft\-weltman\-ldapv3\-proxy\-XX.txt,
the value in the control and thus the constructor argument was a \s-1DN\s0 and was called \f(CW\*(C`proxyDN\*(C'\fR.
It served the same purpose as \f(CW\*(C`authzID\*(C'\fR in recent versions of \f(CW\*(C`proxyAuthorization\*(C'\fR control.
.PP
\&\fBPlease note:\fR
Unfortunately the \s-1OID\s0 and the encoding or the \f(CW\*(C`Proxy Authorization Control\*(C'\fR
changed significantly between early versions of draft\-weltman\-ldapv3\-proxy\-XX.txt
and the final \s-1RFC\s0.
Net::LDAP::Control::ProxyAuth tries to cope with that situation and changes
the \s-1OID\s0 and encoding used depending on the constructor argument.
.PP
With \f(CW\*(C`proxyDN\*(C'\fR as constructor argument the old \s-1OID\s0 and encoding are used,
while with \f(CW\*(C`authzID\*(C'\fR as constructor argument the new \s-1OID\s0 and encoding are used.
Using this logic servers supporting either \s-1OID\s0 can be handled correctly.
.SH "METHODS"
.IX Header "METHODS"
As with Net::LDAP::Control each constructor argument
described above is also available as a method on the object which will
return the current value for the attribute if called without an argument,
and set a new value for the attribute if called with an argument.
