The company I work for runs an on premise 2008 AD. We also have an Office 365 E3 license with user account information from the AD synced to O365 using Azure AD Connect service. We want to migrate our on premise file services to Sharepoint Online, but one requirement is that we are able to map the sites in Widows file explorer on the local workstations (either as a library or mapped network drive). Whilst we can map the sites as drives (by opening the site in IE and viewing in Explorer etc), it appears that the security association times out after a week. The only way we have found to re-establish the security association, is to repeat the afore mentioned steps of logging in via IE (far from ideal).
I’m aware that Microsoft have recently made changes so that the life time of security tokens for Sharepoint Online can now be extended (which will negate the need to re-authenticator every week), but I have seen conflicting information as to whether this can be achieved without an additional Azure AD license. Can anyone shed light on a solution, or point me to a well documented KB on how to extend the security tokens lifetime. At the moment, it’s delaying our adoption of Sharepoint Online (much to the irritation of my users).
