AIX Open Source

Hello I have a problem accessing shares on a AIX 7.1 server which is configured as a domain member. I installed samba version 4.9.6 via yum.

config files:

/etc/netsvc.conf

passwd: files compat winbind
group: files compat winbind

in /usr/lib/security i have a symbolic link:

WINBIND -> /opt/freeware/lib/WINBIND.so

methods.cfg:

WINBIND:
        program = /usr/lib/security/WINBIND
        options = authonly

/etc/krb5.conf

[libdefaults]
        default_realm = DOMAIN.LOCAL
        dns_lookup_realm = false
        dns_lookup_kdc = true

/etc/security/user:

default section:

SYSTEM = "WINBIND OR compat"

registry = WINBIND

wbinfo -g gives all groups of the domain

smbclient -L localhost -U username -d10 fails with:

SPNEGO login failed: The attempted logon is invalid. This is either due to a bad username or authentication information.
session setup failed: NT_STATUS_LOGON_FAILURE

lsuser -R WINBIND ALL | grep "username" shows the user presence ?

lsuser -R WINBIND ALL | grep "username"

ends with no result

If "lsuser -R WINBIND ALL" is also not showing anything, then check whether winbindd deamon is running or not. 

Please attach the samba log as well.

the strange thing is that lsgroup -R WINBIND "ALL" shows all the groups..

it looks like there is no translation to unix ids or something with the range:

Not sure what is the issue. Can you try restarting smbd and winbindd daemons.

After that , try executing the wbinfo --sids-to-unix-ids=<sid_from_log_file> to see whether winbindd is able to resolve it to Unix ids. 

# wbinfo --sids-to-unix-ids=S-1-5-21-1878027269-3674594776-380744556-1104
S-1-5-21-1878027269-3674594776-380744556-1104 -> uid 10001
