On our SharePoint 2010 farm we have implemented managed accounts and these are configured to automatically change password each month. The issue we face is sometimes after the password is changed it is not properly propagated to all the services, for example application pools sometimes are using old passwords, and we only come to know about this issue when one of the application pools on Application server or web servers is stopped and is not able to start again, it could happen on the same day of password change or after weeks of password change, and when this happens we get all kinds of nasty errors like "
Can't connect to database". And we can only make it work by resetting the identity of the application pool and providing it new password manually. Please note we have configured automatic recycling of application pools each night.
I have few questions:
Why password change is not propagated to all the services which use the managed account
Why does not the recycling of application pool force application pool to use new password or how come it can go on with stale password for days even though we have recycling setting for each night
How can we make sure that passwords are propagated to all the services How can we automate this process that we don't have to manually input new password
