Joe User is a part of Corp (which is under Users - could nesting be the problem?):
root at openldap ~# ldapsearch -x -h localhost -p 389 -b "ou=Users,dc=team,dc=company,dc=com" -s sub "cn=joe user"
# extended LDIF
#
# LDAPv3
# base <ou=Users,dc=team,dc=company,dc=com> with scope subtree
# filter: cn=joe user
# requesting: ALL
#
# Joe User, corp, Users, team.company.com
dn: cn=Joe User,ou=corp,ou=Users,dc=team,dc=company,dc=com
givenName: Joe
sn: User
cn: Joe User
uid: joeuser
uidNumber: 1008
gidNumber: 500
homeDirectory: /home/users/joeuser
loginShell: /bin/sh
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: top
# search result
search: 2
result: 0 Success
# numResponses: 2
# numEntries: 1
Is my entry in the authorize section formatted correctly?
Thanks,
Alex
