Hello,
Are you seeing the final redirect to FCC if you are using an HTTP header tool like fiddler ?
Are you seeing anying in the WebServer where the login.fcc is located ? Check the access.log and error.log for Apache Webserver. Do you have the correct alias defined ?
In the sample below, my Webagent is installed under /opt/CA/WA1252SP1CR04
extract of my httpd.conf
Alias /siteminderagent/pwcgi/ "/opt/CA/WA1252SP1CR04/webagent/pw/"
<Directory "/opt/CA/WA1252SP1CR04/webagent/pw/">
Options Indexes MultiViews ExecCGI
AllowOverride None
Require all granted
</Directory>
Alias /siteminderagent/pw/ "/opt/CA/WA1252SP1CR04/webagent/pw/"
<Directory "/opt/CA/WA1252SP1CR04/webagent/pw/">
Options Indexes MultiViews ExecCGI
AllowOverride None
Require all granted
</Directory>
Alias /siteminderagent/ "/opt/CA/WA1252SP1CR04/webagent/samples/"
<Directory "/opt/CA/WA1252SP1CR04/webagent/samples/">
Options Indexes MultiViews
AllowOverride None
Require all granted
</Directory>
Default target for the auth scheme : /siteminderagent/forms/login.fcc
Hope if helps,
Julien.
