Doc Type:	Bug Fix
Doc Text:	Remote users' account settings are no longer reverted to default settings on restart due to ypbind Because of wrong service starting order, ypbind did not start before all Name Service Switch (NSS) look-up operations had been completed. This caused the user's account settings file to revert to default settings on restart for users fulfilling all of the following conditions: * Using Gnome Display Manager auto-login * Using NIS authentication * Home directory located on NFS The ypbind service file ordering has been fixed to make ypbind start before the user/group database is set up. The user's account settings file is now handled properly.

Comment 1 Siteshwar Vashisht 2015-04-30 07:10:36 EDT

Description of problem:
ypbind.service should be loaded before nss-user-lookup.target.

If a gdm autologin user is authenticated using NIS and has it's home directory on NFS, it's '/var/lib/AccountsService/users/$USER' file gets overwritten on reboot. This issue was worked around by using below config file :

# cat /etc/systemd/system/accounts-daemon.service.d/nis-order-fix.conf
[Unit]
After=ypbind.service
After=nss-user-lookup.target
Wants=nss-user-lookup.target

Version-Release number of selected component (if applicable):
ypbind-1.37.1-7.el7.x86_64

How reproducible:
Always

Comment 4 Ray Strode [halfline] 2015-05-29 10:42:28 EDT

we can work around this in accountsservice, but ypbind should be fixed too, or other things aside from accountsservice may hit issues.

ypbind backs an nss module so it needs 

Before=nss-user-lookup.target

otherwise it will be started at the wrong point in boot up.
