Noticed Permissions Issue In Server Log

[vferg 7]

While looking into another issue I noticed in the server log that I was getting some permissions issues while it is trying to access some files within the share.  I guess my question is are these normal, or easy to fix?  Would anyone know what user emby is trying to leverage to look access these directories?  If I know that I can just add it.  From what I see currently I have a user called emby on my Synology, is this the account or is there another service account?  I have a Synology DS1815+ and my Emby server version is currently 4.6.2.0.  Here are several of the errors I see in the log:

Hi, No that's not normal.  Emby is having trouble trying to access your NFO files to update them most likely which could be a permission issue that would need to be corrected.

[vferg 7]

Thanks, do you know what user account that Emby uses to access the files?  I have an account emby listed already on the synology but currently seems to only have read permissions to these directories.  If this is the account I will grant read/write, maybe this is the reason.

[Carlo 4330]

Emby or emby depending on DSM version.

Great, thanks for the help.  I made the change yesterday and looked back today and no longer seeing this.  Adding the extra permissions looks to have fixed this.

Thanks for the feedback.
