[Mono-list] System.Web.Security.Membership causes an exception on mono platform

[Olli Heiskanen]

Hello,

A little more information on this:

The actual problem is an error that says "Failed to map path '/'", that is
what I get in an inner exception:

System.InvalidOperationException
Failed to map path '/'

System.String baseVirtualDir, Boolean allowCrossAppMapping) [0x001a4] in

My Web.config does not have any custom stuff, other than a custom
membership provider, but the same error occurs on a fresh mvc3 site without
any added code or customizations.

My apache/mod_mono configuration is directly from
http://go-mono.com/config-mod-mono/, without any change, here it is:

Alias /boacommander "/var/www/html/boacommander"
  MonoServerPath boacommander "/usr/bin/mod-mono-server4"
  MonoDebug boacommander true
  MonoSetEnv boacommander MONO_IOMAP=all
  MonoApplications boacommander "/boacommander:/var/www/html/boacommander"
  <Location "/boacommander">
    Allow from all
    Order allow,deny
    MonoSetServerAlias boacommander
    SetHandler mono
    SetOutputFilter DEFLATE
    SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip dont-vary
  </Location>
  <IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml
text/javascript
  </IfModule>


I have observed this error on mono versions 3.10.0, 3.10.1 and 3.12.0, all
compiled from git branches.


Based on my searches for a solution, I've seen some posts where this error
occurs on a windows platform and a workaround is to run Visual Studio as
administrator. This is not what I can do as the error does not occur on my
windows platform, and apache process is run as root.

Still I feel this might be a configuration issue, as it has something to do
with path mapping. So far though, I've not found a configuration change
that would solve the issue.

cheers,
Olli
