i have renamed the  database folder and started slapd so i was able to connect to ldap server but seems all the database are vanished 
am now trying to get back  my old database from ldif file 
with this command  ldapmodify 
but i always  get this msg 
ldapmodify: update failed: dc=fg,dc=local
ldap_modify: Constraint violation (19)
        additional info: structuralObjectClass: no user modification allowed
i also want to ask what is the way to to recover the database without making/ creating a new database 
i have tried db-recover tool and it produce this output which i don't understand 
db_recover -cev
db_recover: Finding last valid log LSN: file: 1 offset 28

Sounds as though the BDB database didn't appreciate the sudden power 
loss! ( I know from bitter experience that it is pretty intolerant 
ounder these circumstances ;-))

Berkely comes with a database recovery tool to get this back (check out 
their website for details), maybe someone else here can help?

If you're in dire straits (sounds like you might be!) the quick & dirty 
method is to rename the database directory (if  you're in doubt the path 
to this is stored in your slapd.conf file under the Database directory 
directive), and restart slapd. At this point the process will work but 
you're directory is obviously empty. You need to restore it from a 
recent ldif backup using ldapadd.

Apologies to the more qualified posters for the kluge!

Hopefully this will be helpful.
