## Known limitations

* The Agent Toolkit for PHP supports AES/128/CBC and 3DES/168/CBC.

* The Agent Toolkit for PHP does *not* support AES/256/CBC.

* The **Token Name** field in the adapter configuration must be unique within the given federation, however is not enforced in the user-interface.

* The AES/256/CBC cipher suite is not supported, due to limitations in the PHP mcrypt libraries.

* All plain-text files have UNIX-style line feeds. This may result in difficulty editing files on a Windows computer.

* Password obfuscation is not supported by the agent.

* The sample application does not support local logout when set to cookie transport mode

* If the SP adapter is set to send extended attributes as cookies, multi-value attributes will fail, because multiple cookies with the same name are not allowed.
