Dear all
I have a system with samba PDC with LDAP, samba version being 3.0.21 and
openLDAP version 2.2.13
i have another linux system with samba version being 3.0.10 which is a
member server to samba pdc.
i have configured nss_ldap, and ldap.conf configured on the member server
pointing to my ldap server on samba pdc
The samba PDC LDAP is configured for simple bind .
1 )i have been getting the following errors:
on the member server when i issue the command net rpc info i get the
following error
rpc_parse/parse_prs.c prs_mem_get(537)
prs_mem_get: reading data size 14418130 would overrun buffer
what does the above error mean
2) on the domain member server i get the
error: nss_wins ldap_simple_bind can't contact LDAP server
3) And often on the samba PDC /var/log/message i get the following error
init_sam_from_ldap , Failed to get password history for user
4) on samba PDC , With LDAP , i get the following error,
slapd[] bdb_equality_candidates : (uid) index_param failed
bdb_equality_candidates : (sambaGroupType) index_parm failed
i believe the above error means that there some indexing problem with my
slapd.conf file in my samba PDC,
but what exaclty that is causing the problem , unable to figure it out.
my slapd.conf of samba pdc is

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command
"testparm"
# to check that you have not made any basic syntactic errors.
