to help a little here an example of entry Aliases :

$ ldapsearch -h aragon -x -b ou=Aliases,dc=ad,dc=dr15,dc=cnrs,dc=fr > 
/tmp/aliases.txt

$ cat /tmp/aliases.txt
# extended LDIF
#
# LDAPv3
# base <ou=Aliases,dc=ad,dc=dr15,dc=cnrs,dc=fr> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# Aliases, ad.dr15.cnrs.fr
dn: ou=Aliases,dc=ad,dc=dr15,dc=cnrs,dc=fr
objectClass: top
objectClass: organizationalunit
ou: Aliases

# Test1, Aliases, ad.dr15.cnrs.fr
dn: cn=Test1,ou=Aliases,dc=ad,dc=dr15,dc=cnrs,dc=fr
objectClass: postfixAlias
objectClass: top
cn: Test1
mailacceptinggeneralid: test-ldap-1
maildrop: joe
maildrop: jack

# Test2, Aliases, ad.dr15.cnrs.fr
dn: cn=Test2,ou=Aliases,dc=ad,dc=dr15,dc=cnrs,dc=fr
objectClass: postfixAlias
objectClass: top
cn: Test2
mailacceptinggeneralid: test-ldap-2
maildrop: william
maildrop: averell
maildrop: test-ldap-1
