How to flush database in LDap

[faizal <faizal.abdollah@mmu.edu.my>]

hi...I having a problem to flush the ldap database after i editing the
ldif file..
It won't catch the new entry that i have made inside the database
For example :

before editing
dn: cn=faizal,dc=mmu,dc=edu,dc=my
cn: faizal
objectClass: top
objectClass: person
objectClass: inetOrgPerson
sn: faizal

after editing

dn: cn=faizal,dc=mmu,dc=edu,dc=my
cn: faizal
objectClass: top
objectClass: person
objectClass: inetOrgPerson
sn: faizal
mail: faizal.abdollah@mmu.edu.my

result:

the mail wouldn't come out after i search for the data.

I have restart my ldap but still cannot get the new data..
Please help me
