# Known issues and limitations

The following are known issues or limitations for the Apache Linux Integration Kit.

## Known issues

* URL encoding in the `PingFederateFilter` and `PingFederateFilterAnonymous` isn't supported.

* In some configurations, Apache fails to load the module with the following being the last log entry: `Deobfuscating password for the password-based keys generation`.

  To overcome this issue, ensure the agent module is loaded immediately after the authz-related modules.

## Known limitations

* `Satisfy All` isn't supported when used in conjunction with the `Allow` directive for access control.

* `RequireAll` isn't supported.

* The `PingFederateFilter` doesn't support:

  * URL encoded characters or non-ASCII characters.

  * Query strings

* The PingFederate Apache agent relies on path comparison to protect resources. Other modules in Apache such as `mod_speling` and `mod_rewrite` can affect the way the PingFederate Apache agent evaluates resources.

* To support fragment preservation, the # symbol in URL fragment must be URL encoded.
