users can not login on AIX operating system (4286052)

users can not login on AIX operating system

vastool list users/groups shows users/groups, but vastool nss getXXYYY commands fail with 2 ( ENOENT ).

System configuration change to the /etc/security/user file.

In the default stanza of the /etc/security/user file, there was a duplicate SYSTEM entry which said SYSTEM = "compat".

There was a correct entry below which said SYSTEM = " VAS OR compat"

Commented out the entry which said SYSTEM = compat. We used the * to comment it out.

The file's default stanza then looked like the following:

default:
admin = false
login = true
su = true
daemon = true
rlogin = true
sugroups = ALL
admgroups =
ttys = ALL
auth1 = SYSTEM
auth2 = NONE
tpath = nosak
umask = 022
expires = 0
* SYSTEM = "compat"
logintimes =
pwdwarntime = 0
account_locked = false
loginretries = 0
histexpire = 0
histsize = 0
minage = 0
maxage = 0
maxexpired = -1
minalpha = 0
minother = 0
minlen = 0
mindiff = 0
maxrepeats = 8
dictionlist =
pwdchecks =
SYSTEM = "VAS OR compat"
logintimes =
pwdwarntime = 0
account_locked = false
loginretries = 0
histexpire = 0
histsize = 0
minage = 0
maxage = 0
maxexpired = -1
minalpha = 0
minother = 0
minlen = 0
mindiff = 0
maxrepeats = 8
dictionlist =
pwdchecks =

Note:
The * must be at the first of the line to be considered a comment.

The OS was using the first entry of SYSTEM, and ignoring VAS as a repository.
