Symptom

While trying to upload an Anyconnect image to FMC under Objects > Object Management > VPN > AnyConnect File while logged in with an External Authentication user you receive the error message: Error during file upload. Please ensure that the FMC has enough space, the file is valid and that the file name contains only letters, digits, '-' and '_'. AnyConnect Image file names may contain '.' If you verify on /var/log/httpd/httpsd_error_log, you will see the following error messages for the upload. [Mon May 10 19:11:06.609947 2021] [cgi:error] [pid 20554] [client [ip address]] AH01215: Uploading Any connect file at /usr/local/sf/htdocs/ddd/fileUpload.cgi line 232.: /usr/local/sf/htdocs/ddd/fileUpload.cgi, referer: https://[fmc url]/ddd/ [Mon May 10 19:11:06.609956 2021] [cgi:error] [pid 20554] [client [ip address]] AH01215: Impossible to create directory : /usr/local/sf/htdocs/ddd/fileUpload.cgi, referer: https://[fmc url]/ddd/ [Mon May 10 19:11:06.609993 2021] [cgi:error] [pid 20554] [client [ip address]] AH01215: The 'dir' parameter ("/var/opt/CSCOpx/MDC/temp/ANY_CONNECT_IMAGE/user@domain") to SF::System::Privileged::mkdir did not pass the 'Type Validator (system.filename)' callback: /usr/local/sf/htdocs/ddd/fileUpload.cgi, referer: https://[fmc url]/ddd/

Conditions

Using external authentication for users that need to enter [username]@[domain].

Workaround

Use local user to upload AnyConnect images. No workaround while using external authentication users with the above format at the moment.
