| 1 | Summary of pieces related to ISS. I have attempted to boil it down to the correspondence between the two and the places to look when interested in checking the settings. |

| 4 | When working with Windows' IIS, Shibboleth requires the use of an IIS ISAPI Filter. The filter is provided by way of DLL in the shibboleth-sp installation folder. A 32 and 64 bit version are provided in the Shibboleth SP distribution. |
| 5 | |
| 6 | 32 bit example path to ISAPI Filter: |
| 7 | C:\opt\shibboleth-sp\lib\shibboleth\isapi_shib.dll |
| 8 | 64 bit example path to ISAPI Filter: |
| 9 | C:\opt\shibboleth-sp\lib64\shibboleth\isapi_shib.dll |
| 10 | |
| 11 | The following two screen shots depict how to get to the IIS 7 configuration screen for ISAPI filters. |
| 12 | 1. Select the main server configuration. |
| 13 | 2. Choose the ISAPI Filters from the IIS section. |
| 14 | 3. The second image shows the configuration to support only the 64bit version of shibboleth's ISAPI Filter. |
| 15 | |
| 16 | ... |
| 17 | To add the 32 bit version of shibboleth, you can right click and choose the Add option. You will provide a name and the path to the 32 bit version of Shibboleth's isapi_shib.dll file. |
| 18 | |
| 19 | The version that an ASPX or similar IIS application will need, depends on how the application pool for the specific application is configured. To inspect the application pool of interest. |
| 20 | 1. Select the Application Pools list in the left hand menu. |
| 21 | 2. Right click the application pool of interest. |
| 22 | 3. Select the Advanced Settings menu item. |
| 23 | ... |
| 24 | 4. Review the setting labeled "Enable 32-Bit Applications" |
| 25 | When set to False, this implies a 64 bit application. |
| 26 | When set to True, the implies a 32 bit application. |
| 27 | The corresponding version of the Shibboleth isapi_shib.dll file must be available in the server to successfully have the application work as expected. |
