I currently have the path on my rest/Soap server. I would like to move that folder to my report server but I can't find out what access is needed for Tessitura to access that folder on another server.
I believe Tessitura interacts with the file system or file shares under only two different user accounts for the purposes of the report server: the SQL "proxy user" that the database runs as, and the application pool user that the TessituraWeb/TOTG application runs under (SSRS reports will fail if the TessituraWeb AppPoolIdentity is not granted access).
You may also need to grant the user account your report server is running under access to the share, but at least this is easy to test because that is a full user account.
I can add the account that the database runs under as well as the report server account. Those are all domain account. The application pool it's running under application pool identity and not tied to a domain account.
Is it okay to use a custom account instead of applicationpoolidentity for the application pools?
I am running my TessituraWeb application under a custom account and it works properly for me. Reportedly, you can grant the default app pools access to a share by using the "machine account", but this only works in a domain environment. (We don't have an AD domain so using the custom account is _required_ for running SSRS reports in the report server.)
Check out this documentation for using the default app pool and machine account: http://www.iis.net/learn/manage/configuring-security/application-pool-identities
Otherwise, using a custom account should work fine.
We have a domain and I do have rest/soap server machine account added to the share but it's not in the form of IIS APPPOOL\YourAppPoolName. I don't know if it will work but I will try.
Since you have application pool running under a custom name. I assume you just assign the name to the share and it's fine then?
