Description Akshay Sakure 2020-12-16 21:39:52 UTC

- Description of problem:
smbclient command shows an error "gencache_init: Failed to create directory: /home/username/.cache/samba - No such file or directory" on accessing samba share when executed by non-privileged user

- Version-Release number of selected component (if applicable):
samba-4.10.16-9.el7_9.x86_64

- How reproducible:
Always.

- Steps to Reproduce:
1. Create a share on Windows AD server.
2. Join a system to AD domain via realmd (samba + winbind)
3. Try to access the share hosted on Windows system via smbclient

- Actual results:
'smbclient' command shows an error/warning while accessing the share as non-privileged user e.g. local linux user. 
---
gencache_init: Failed to create directory: /home/localuser1/.cache/samba - No such file or directory
---

- Expected results:
'smbclient' command shouldn't throw any error while accessing the share as non-privileged user. 

- Additional info:
This error doesn't occurs for "root" user. 
The error is not seen if you manually create '.cache/samba' directory under user's home-directory.

This looks like a regression to https://bugzilla.redhat.com/show_bug.cgi?id=1831986 which was fixed in samba-4.10.16-5.el7
