You mean something like this?


[root at pc1 /]# ldapsearch -x -b "cn=Darod Zyree,ou=users,dc=local,dc=test"
# extended LDIF
#
# LDAPv3
# base <cn=Darod Zyree,ou=users,dc=local,dc=test> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# Darod Zyree, users, local.test
dn: cn=Darod Zyree,ou=users,dc=local,dc=test
cn: Darod Zyree
givenName: Darod
gidNumber: 500
sn: Zyree
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: top

# search result

This works on both the server and the workstation without any issue,
not even causing 100% slapd cpu.
