Openldap gurus:
Here is my setup,
LDAPSERVERS: I have two ldap servers running RHEL7.2 and openldap 2.4.40. Both servers are configured with multi-master replication. Ldaps is enabled and a ppolicy applied.
LDAPCLIENT: My ldap client is running RHEL7.2 as well, sssd 1.13.0, and openldap client 2.4.40.
I have been troubleshooting this problem for a while and can’t figure out why everytime I try to login to an ldap client with a test user account the slapd service on only one of my ldap servers gets killed.
Both getent and ldapsearch return the expected information when ran on the ldap client: ldapclient ~]# getent passwd realtest realtest:*:1004:312:Liz RealTest:/home/real:/bin/tcsh
ldapclient ~]# ldapsearch -x -s sub -b 'ou=People,dc=cluster,dc=sec312' '(uid=realtest)' # extended LDIF # # LDAPv3 # base <ou=People,dc=cluster,dc=sec312> with scope subtree # filter: (uid=realtest) # requesting: ALL #
# realtest, People, cluster.sec312 dn: uid=realtest,ou=People,dc=cluster,dc=sec312 gidNumber: 312 objectClass: account objectClass: top objectClass: posixAccount objectClass: shadowAccount uid: realtest loginShell: /bin/tcsh homeDirectory: /home/real cn: Liz RealTest uidNumber: 1004
