IRM Limitations in SharePoint 2013 On premises.

 

PDF document cannot be in IRM enabled libraries in ADOBE Reader, to make it work we have to rely on third party readers like foxit,nithyo

 

Excel Sheets we cannot open in the browser if these sheets are stored in the SP library where IRM is enabled.

 

We don’t have direct control over IRM permissions in SharePoint 2013,  according to SP permissions given for user on library IRM permissions will work. Means IRM is relied on SP for permissions.   

 

These are true to my investigation from Microsoft Forums and TechNet Articles.

Apps configuration in SharePoint 2013

Apps Configuration high level steps and points to consider while setting up Apps in SharePoint 2013 on premises.

1. Create forward lookup zone in the DNS server
2. Create alias on this zone , provide the wildcard as *  and provide FQDN for target host as SharePoint Server.
3. Configure subscription service by using PowerShell
4. Configure apps service by using PowerShell

In SP CA :

In the Apps section in central admin, in the apps domain section, provide the domain name (zone) which you have configured in DNS

Provide any convenient prefix name  in the App Prefix like “app” and hit ok.

Point to Note :

Apps should have dedicated web application and app catalog should be created in this web application.

And that web application should not have any host headers (host names)
