Hi jerry I have reproduced the same error, in samba 3.0.21b with openldap 2.3.19 . i have created 70 groups starting from test1-test70 and created a user called nir and add nir to these 70 groups, and tried to login with smbclient the below command i gave when the samba was running in daemon mode and not in interactive mode. smbclient //testbdc/nir -U nir%nir it showed the following error "session setup failed call timed out server did not respond after 20000 milliseconds"
in slapd.conf i have setup timelimit to 50seconds and in smb.conf ldap timeout is 50 seconds next time i have run the samba in interactive mode with debug level 10 then i gave the following command smbclient //testbdc/nir -U nir%nir it gave the following error "Session setup failed call returned zero bytes" and samba got killed with the following error *** glibc detected *** double free or corruption (!prev): 0x09af63b0 *** Aborted >From Windows system it was the same error ""Remote procedure call was cancelled"" The attached file is called stacktrace. plese check it , The above error occurs only to users who belong to many groups, this error does not come when user is in 10 or 20 groups. The following is my smb.conf ########################################## #======================= Global Settings ===================================== [global] workgroup = msdpl.com netbios name = testbdc passdb backend = ldapsam:ldap://msdpl.com server string = Domain Controller hosts allow = 192.168.128. 192.168.129. 192.168.130. 127. security = user encrypt passwords = yes socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 interfaces = eth0, lo printing = cups disable spoolss = Yes printcap name = cups max print jobs = 100 enable privileges = yes password level = 8 username level = 8 bind interfaces only = yes local master = Yes os level = 65 domain master = yes preferred master = yes null passwords = no hide unreadable = yes hide dot files = yes domain logons = yes logon script = %u.bat logon path = logon drive = X: logon home = \\testbdc\%U wins support = yes name resolve order = wins lmhosts host bcast log level = 10 dns proxy = no time server = yes log file = /var/log/samba/%U.%m.log max log size = 0 nt acl support = yes ldap passwd sync = yes add user script = /usr/local/sbin/smbldap-useradd -m "%u" delete user script = /usr/local/sbin/smbldap-userdel "%u" add machine script = /usr/local/sbin/smbldap-useradd -w "%m" add group script = /usr/local/sbin/smbldap-groupadd -p "%g" add user to group script = /usr/local/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/local/sbin/smbldap-groupmod -x "%u" "%g" set primary group script = /usr/local/sbin/smbldap-usermod -g '%g' '%u' ldap delete dn = Yes ldap ssl = no ldap suffix = dc=msdpl,dc=com ldap admin dn = cn=manager,dc=msdpl,dc=com ldap group suffix = ou=Groups ldap user suffix = ou=People ldap machine suffix = ou=Computers ldap idmap suffix = ou=Idmap ldap timeout = 50 idmap backend = ldap:ldap://192.168.129.18 idmap uid = 10000-20000 idmap gid = 10000-20000 map acl inherit = yes winbind use default domain = yes template shell = /bin/bash ################[Share Definations]################## [homes] comment = Home Directories valid users = %S browseable = no read only = no nt acl support = Yes # Un-comment the following and create the netlogon directory for Domain Logons [netlogon] comment = Network Logon Service path = /usr/local/samba/lib/netlogon/scripts guest ok = yes browseable = no write list = root [printers] comment = All Printers path = /var/spool/samba create mask = 0600 guest ok = Yes printable = yes use client driver = Yes browseable = no ######################################################################### slapd.conf ############################################################################## # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # include /usr/local/ldap-2.3/etc/openldap/schema/core.schema include /usr/local/ldap-2.3/etc/openldap/schema/cosine.schema include /usr/local/ldap-2.3/etc/openldap/schema/inetorgperson.schema include /usr/local/ldap-2.3/etc/openldap/schema/nis.schema include /usr/local/ldap-2.3/etc/openldap/schema/samba.schema # Define global ACLs to disable default read access. # Do not enable referrals until AFTER you have a working directory # service AND an understanding of referrals. #referral ldap://root.openldap.org pidfile /usr/local/ldap-2.3/var/run/slapd.pid argsfile /usr/local/ldap-2.3/var/run/slapd.args # Load dynamic backend modules: # modulepath /usr/local/ldap-2.3/libexec/openldap # moduleload back_bdb.la # moduleload back_ldap.la # moduleload back_ldbm.la # moduleload back_passwd.la # moduleload back_shell.la # Sample security restrictions # Require integrity protection (prevent hijacking) # Require 112-bit (3DES or better) encryption for updates # Require 63-bit encryption for simple bind # security ssf=1 update_ssf=112 simple_bind=64 # Sample access control policy: # Root DSE: allow anyone to read it # Subschema (sub)entry DSE: allow anyone to read it # Other DSEs: # Allow self write access # Allow authenticated users read access # Allow anonymous users to authenticate # Directives needed to implement policy: # access to dn.base="" by * read # access to dn.base="cn=Subschema" by * read # access to * # by self write # by users read # by anonymous auth # # if no access controls are present, the default policy # allows anyone and everyone to read anything but restricts # updates to rootdn.
