Hi to everyone!
I have a great problem, in my job I have a server with LDAP(openldap-2.3.27)
The problem is when I charge one group with around 1654 registers the next error shows:
 
ldap_modify: Internal (implementation specific) error (80)
 
I tried the next solutions...
1.- I charge the DB  with slapadd, since one backup but when I Charge other group with 1500 users the error occurs again...
ldap_modify: Internal (implementation specific) error (80)
 
2.- I delete the group from the backup and charge the DB withouth problems, but when I charge the group by separated, the error occurs again.
ldap_modify: Internal (implementation specific) error (80)

3.- I started the slapd in debug level 3  and charge the group by separately and this is the exit....
