During further investigation of the issue following observations were made.
1. The problem doesn't happen when both grid home and oracle home are installed under one user (usually as oracle user).
2. Problem doesn't happen in RAC environments even if grid home and oracle home are installed as different users (grid home as grid user and oracle home as oracle user)
3. Problem only happens in single instance environments (tested on 12c and 11.2.0.4) where grid home is owned by grid user and oracle home is owned by oracle user.
Looking at the trace file shows that srvctl fails to connect to idle instance to start the database

As mentioned earlier local option prevents wallet being used in another host and is tied to the OS user.

All rights reserved. srvctl start database -d se2db srvctl status database -d se2db Database is running.So it appears the problem seem to be use of auto_login_local since there's no issue when using auto_login. Since wallet wasn't moved to a different server, the only reason that could prevent DB from starting with a wallet created with auto_login_local option is if the starting command is executed by a user other than the user tied to the wallet. Right now the wallet has been created as Oracle user and srvctl start was executed as oracle user. So it appears that grid user gets involved in starting the DB even when srvctl is run as oracle user (why the same is not happening in RAC role separated config is under SR)
So the solution in this case was to create an empty wallet as grid user and set permission to 750.

Why the auto_login_local fails this way in Oracle restart with role separation is still under SR.
