Adding to this, I've found that 'getent group' works just fine despite using the same socket:

# grep pipe getent_passwd.strace getent_group.strace
getent_passwd.strace:connect(4, {sa_family=AF_UNIX, sun_path="/var/lib/sss/pipes/nss"}, 110) = 0 getent_passwd.strace:connect(3, {sa_family=AF_UNIX, sun_path="/var/lib/sss/pipes/nss"}, 110) = -1 ECONNREFUSED (Connection refused) getent_group.strace:connect(4, {sa_family=AF_UNIX, sun_path="/var/lib/sss/pipes/nss"}, 110) = 0

Yesterday we upgrade some of our systems to OpenSuSE 15.6. We have sssd configured to to enumate, but when I do 'getent passwd, I get only the contents of /etc/passwd, a hang for 3-5 seconds, and then the command ends w/o any of our user information from LDAP. using strace, I see getent is failing with this error:

connect(3, {sa_family=AF_UNIX, sun_path="/var/lib/sss/pipes/nss"}, 110) = -1 ECONNREFUSED (Connection refused)

Even with logging turned all the way up, the only message I see in the logs is this:

(2025-11-04 16:51:16): [sssd] [svc_child_info] (0x0020): Child [71156] ('nss':'nss') was terminated by own WATCHDOG

I know this isn't a communication issue between the client and the server. With logging turned all the way up, I see that sssd is getting all the account information from LDAP.

Any ideas what is wrong here? The client system does have apparmor enabled, but I'm not as familiar with apparmor as I am with SELinux, so I don't know a reliable way to confirm/disprove that AA might be part of this problem.
