Problem starting ldap 2.4

[Nick Milas <nick@eurobjects.com>]

Hi,

I am trying to migrate from CentOS 5.5 Openldap 2.3.43-12.el5_5.3 to 
2.4.22-1.el5.x86_64 using Buckan RPMs (available at 
http://staff.telkomsa.net/packages/rhel5/openldap/x86_64/).

I think I have done all necessary configuration, but when I try to 
start, I get a strange error:

   # service ldap2.4 start
   ' for reading (No such file or directory)f FNR=196) fatal: cannot
   open file `/etc/openldap2.4/schema/core.schema
   chown: cannot access `/var/lib/ldap2.4\r': No such file or directory
   Starting slapd (ldap + ldaps):                             [FAILED]

Note, however that /etc/openldap2.4/schema/core.schema exists:

   # ls -la /etc/openldap2.4/schema/core.schema
   -rw-r--r-- 1 ldap ldap 19762 Nov 29 10:49
   /etc/openldap2.4/schema/core.schema

The core.schema is the first one included in slapd.conf, so there is 
probably a problem with all included schema files.

The config file is supposed to be OK:

   # slaptest2.4 -f /etc/openldap2.4/slapd.conf
   config file testing succeeded

The db data has been successfully input using slapadd, from an ldif 
backp. The db is in /var/lib/ldap2.4:

   # slapadd2.4 -l /root/ldapbk/ldif.ldap.bk
   -#################### 100.00% eta   none elapsed             45s

   drwxr-x---  3 ldap ldap    4096 Dec 27 13:03 ldap2.4

I have googled around but can't find something about this error.

Can someone please help?

Thanks in advance,
