Hello Team:

After an upgrade to AIX 7200-05-04-2220 from 7100-05-05-1939, SAMBA 4.14.4
now prompts for userid and password from Windows 10 and Windows 11 clients
attempting to map a drive. This was not required by SAMBA before the
upgrade. Two other systems that have AIX 7.2 upgrades with SAMBA 4.14.4 are
functioning correctly and do not prompt for userid and password.(for
existing userids/accounts). The method used to perform the upgrades for all
3 systems was the same (NIM Alternate Disk Migration), Also, the smb.conf
on all 3 systems is the same. In the log I see the following failure:

[2022/11/28 16:48:30.181656, 1]
gss_accept_sec_context failed with [ Miscellaneous failure (see text):
Failed to find cifs/xxxx at YYYYY.COM(kvno 4) in keytab MEMORY:cifs_srv_keytab

workgroup = ZZZ
realm = YYYYY.COM
interfaces =
netbios name = xxxx
security = ADS
log file = /var/samba/log/log.%m
log level = 3 passdb:5 auth:5
wins server = corp-inm-dc2.inmar.com
password server = corp-inm-dc2.inmar.com
socket address =
server min protocol = SMB2
server signing = mandatory
create mask = 0666
follow symlinks = yes
unix extensions = no

(the xxxx, YYYYY and ZZZ are redactions of the actual system name for
security reasons)

Any assistance on finding what is causing this would be greatly
