Michael,

Thanks for your response. When starting the OpenLDAP server I can see the following in the log file:

May 28 06:35:30 localhost slapd-ldap[2804]: @(#) $OpenLDAP: slapd 2.4.23 (Dec 7 2011 21:35:18) $#012#011mockbu...@c6b18n3.bsys.dev.centos.org:/builddir/build/BUILD/openldap-2.4.23/openldap-2.4.23/build-servers/servers/slapd May 28 06:35:30 localhost slapd-ldap[2804]: /etc/openldap/slapd.conf: line 150: warning, destination attributeType 'sAMAccountName' is not defined in schema May 28 06:35:30 localhost slapd-ldap[2804]: PROXIED attributeDescription "SAMACCOUNTNAME" inserted. May 28 06:35:30 localhost slapd-ldap[2804]: /etc/openldap/slapd.conf: line 159: warning, destination attributeType 'UnixHomeDirectory' is not defined in schema May 28 06:35:30 localhost slapd-ldap[2804]: PROXIED attributeDescription "UNIXHOMEDIRECTORY" inserted. May 28 06:35:30 localhost slapd-ldap[2804]: /etc/openldap/slapd.conf: line 162: warning, destination objectClass 'user' is not defined in schema
May 28 06:35:30 localhost slapd-ldap[2805]: slapd starting

Should I add that info into the schema? If so, how do I go about doing this?

Greetings,

Jonathan

I'm new to OpenLDAP and am trying to implement the following:

User authentication (PAM + SSSD) on CentOS Linux servers via OpenLDAP proxy to
Active Directory. I am able to perform the following search from the OpenLDAP
proxy without any apparent issues:
*
[root@openldap ~]# ldapsearch -x -h /mydomaincontroller/ -LLL -b
dc=msad,dc=inet,dc=com -D cn=ldap,cn=users,dc=msad,dc=inet,dc=com -W
'(sAMAccountName=jonathanv)' cn sAMAccountName

Enter LDAP Password:
dn: CN=jonathan,CN=Users,DC=msad,DC=inet,DC=com
cn: jonathan
sAMAccountName: jonathanv

# 
refldap://ForestDnsZones.msad.inet.com/DC=ForestDnsZones,DC=msad,DC=inet,DC=com

# 
refldap://DomainDnsZones.msad.inet.com/DC=DomainDnsZones,DC=msad,DC=inet,DC=com

# refldap://msad.inet.com/CN=Configuration,DC=msad,DC=inet,DC=com*

However, when asking the OpenLDAP proxy:

*[root@openldap ~]# ldapsearch -x -h /localhost/ -LLL -b
dc=msad,dc=inet,dc=com -D cn=ldap,cn=users,dc=msad,dc=inet,dc=com -W
'(sAMAccountName=jonathanv)' cn sAMAccountName

Enter LDAP Password:
# 
refldap://ForestDnsZones.msad.inet.com/DC=ForestDnsZones,DC=msad,DC=inet,DC=com

# 
refldap://DomainDnsZones.msad.inet.com/DC=DomainDnsZones,DC=msad,DC=inet,DC=com

# refldap://msad.inet.com/CN=Configuration,DC=msad,DC=inet,DC=com*
Have a look in the proxy log. I guess you did not add the attribute type
description for sAMAccountName to the proxy's schema.

Ciao, Michael.
