+### _Query a LDAP directory as a user_
+
+we already created the user (_uid_) marisa, and established the user's own password using slappasswd\
+now we are gonna query our LDAP server using the user (_uid_) marisa credentials, and _the password we entered during slappasswd, called plain password_ 
+```
+root@example:/etc/ldap# ldapsearch -D uid=marisa,ou=Supergirls,dc=example,dc=com -b "dc=example,dc=com" -w plainpasswd
+# extended LDIF
+#
+# LDAPv3
+# base <dc=example,dc=com> with scope subtree
+# filter: (objectclass=*)
+# requesting: ALL
+#
+
+# example.com
+dn: dc=example,dc=com
+objectClass: top
+objectClass: dcObject
+objectClass: organization
+o: nodomain
+dc: example
+
+# Supergirls, example.com
+dn: ou=Supergirls,dc=example,dc=com
+...
+```
+
+we can narrow this search to get only specific attributes of the user marisa, remember we are using _the plainpasswd when asked_
+```
+root@example:/etc/ldap# ldapsearch -D uid=marisa,ou=Supergirls,dc=example,dc=com -b "dc=example,dc=com" -w plainpasswd givenName uidNumber gidNumber homeDirectory
+# extended LDIF
+#

+# base <dc=example,dc=com> with scope subtree
+# filter: (objectclass=*)
+# requesting: givenName uidNumber gidNumber homeDirectory
