Hello!
We have samba 4.12.10-1 on AIX 7.1.
When I try to connect to a share we receive the error:

I think this is "getgrset returning NULL" issue. Log level 10 will reveal it. 
This is a problem that persists with the recent samba versions in AIX.
smbd checks for the user presence locally somehow. Doing a "mkuser <username>" is a workaround for this.

Thanks @Ayappan P
You're right. In log level 10 appears:
[2021/02/09 20:22:37.884941, 10, pid=64684060, effective(0, 0), real(0, 0)] ../../source3/lib/system_smbd.c:46(getgrouplist_getgrset)
getgrset returned (NULL)

​And If I create user at AIX level then I can access to share withour errors.

Do you know if a new smbd versions solve this problem? If yes then I could compile it on AIX.

Thanks in advance

Regards,
Juan

I think this issue is not yet fixed and persists in the newer version as well.
