multiple groups not showing up in "groups" cmd
by Justin Lintz 03 Feb '09

03 Feb '09

Hi, I've configured a user to be a member of another posixGroup as so... dn: cn=dev2,ou=groups,dc=test,dc=net cn: dev2 gidNumber: 1003 objectClass: posixGroup objectClass: top memberUid: dave The users info: dn: cn=David FooBar,ou=people,dc=test,dc=net givenName: David sn: FooBar cn: David FooBar uid: dave userPassword:: uidNumber: 1009 gidNumber: 1004 homeDirectory: /home/dave loginShell: /bin/bash objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount objectClass: top If I log into a server with the users account, it shows him properly a member of gid 1004, but does not list his seconday group of dev2. My /etc/ldap.conf file is base dc=test,dc=net binddn cn=Manager,dc=test,dc=net bindpw timelimit 15 bind_timelimit 15 idle_timelimit 3600 nss_initgroups_ignoreusers root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman pam_filter objectclass=posixaccount pam_member_attribute memberuid nss_base_passwd ou=People,dc=test,dc=net?one nss_base_shadow ou=People,dc=test,dc=net?one nss_base_group ou=Groups,dc=test,dc=net?one uri ldaps://prodldap01/ ldaps://prodldap02/ ssl on tls_cacertdir /etc/openldap/cacerts tls_checkpeer no pam_password md5 I also tried changing the value of memberUid to the DN of the user, but that did not work as well. Any suggestions are appreciated. Thanks - Justin Lintz

Hi, I am using Symas' OpenLDAP s/w on a solaris 10 box. The package I have installed is symas-openldap-silver-2.4.12.0.sun4u.pkg. # pkginfo -l symas-openldap-silver PKGINST: symas-openldap-silver NAME: Symas OpenLDAP Silver CATEGORY: application ARCH: sun4u VERSION: Dev Release 10/17/2008 BASEDIR: / PSTAMP: gamba20081017182137 INSTDATE: Dec 09 2008 16:36 STATUS: completely installed FILES: 279 installed pathnames 24 directories 72 executables 60155 blocks used (approx) I want to get syslogging from slapd out to a file. I have configured /etc/syslog.conf with the following lines: # LDAP logging local4.debug /var/log/slapd.log The file /var/log/slapd.log exists: # ls -l /var/log/slapd.log -rw-r--r-- 1 root root 0 Dec 10 09:25 /var/log/slapd.log and I have restarted syslog: # svcadm restart svc:/system/system-log In /opt/symas/etc/openldap/slapd.conf I have included a line: loglevel -1 and restarted my slapd server using: /opt/symas/etc/solserver restart Having done all this I am still not getting anything written out to /var/log/slapd.log. Does anyone know what I need to do to get this working please? My regards Ian G Fox

Generally, the web application is part of the service which encompasses the web server and directory service.

If it is, where should I start? Would require cooperation between the web server and the directory server.
