Package: slapd
Version: 2.1.30-3
Followup-For: Bug #255276

I am using LDAP for authentication with libnss_ldap. I also use
webmin-ldap-useradmin 1.160-1 for managing the LDAP database.

I am trying to add Samba login information to a user account using
webmin, but when I set "Samba login?" to "Yes" in the webmin Edit User
screen and press Save, I get
  "Failed to save user : Failed to modify user in LDAP database : I/O
  Error"
and subsequent attempts to access the LDAP database through webmin fail with
  "Failed to connect to LDAP server 127.0.0.1 port 389."
    

Moreover the LDAP server stops accepting connections:

~$ ldapsearch
ldap_sasl_interactive_bind_s: Can't contact LDAP server (81)
~$ ldapsearch -W -x
Enter LDAP Password:
ldap_bind: Can't contact LDAP server (81)

As a result, it is no longer possible to log in to the system.

Listing the database with slapcat works sometimes, but I have also
experienced that slapcat just hangs, giving no output at all.

Restarting slapd does not help, but if I run db4.2_recover and then
restart slapd, it works normally again.

The LDAP database is very small, containing only 3-4 user entries.

I tried putting the line
  export LD_ASSUME_KERNEL=2.4.1
in /etc/default/slapd and restarting slapd, but it did not help.
