Samba 3, openLDAP auf einem SLES9 - Samba Absturz

[sinteam]

Hallo Liste,

seit einigen Tagen kämpfe ich mit Samba 3 und openLDAP auf einem SuSE Linux Enterprise Server 9.0.

Zuerst habe ich den openLDAP Dienst installiert und konfiguriert. Ich habe auch die erweitere Funktion mit Yast konfiguriert. Ich kann im Yast User ung Gruppen anlegen und diese können sich auch direkt an der Console oder über SSH anmelden. Funktionert wunderbar.

Wenn ich dann aber den Sambadienst konfiguriere, stürzt dieser immer ab. In /var/log/messages erhalte ich folgende Fehlermeldung:

# Load dynamic backend modules:
modulepath /usr/lib/openldap/modules
# moduleload back_ldap.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 to user password
# Allow anonymous users to authenticate
# Allow read access to everything else
# Directives needed to implement policy:
#access to dn.base=""
# by * read
#
#access to dn.base="cn=Subschema"
# by * read
#
#access to attr=userPassword,userPKCS12,sambaLMPassword,sambaNTPassword

#access to attr=shadowLastChange
# by self write
# by * read
#
access to *
by dn="cn=admin,dc=cpqriz2,dc=int" write
by self write
by * read

# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn. (e.g., "access to * by * read")

Hat jemand eine Idee was ich falsch mache?

Ich hoffe, dass mir jemand weiterhelfen kann. Recht herzlichen Dank.

Hi,

nach der Installation habe ich mit Yast ein Onlineupdate durchgeführt. Leider habe ich nicht überprüft, welche Pakete upgedatet wurden.

Samba ohne LDAP funktioniert. Das habe ich getestet. Sobald ich die LDAP Anweisungen aus der smb.conf entferne läuft der Sambaserver sauber dahin.

Vielleicht gibt es ja einen Softwarebug???

Hi,

ich glaube ich habe das Problem gelöst. Scheinbar gibt es einen Paketfehler in Version 3.0.9 von SuSE. Ich habe das 3.0.4 Paket installiert und nun läuft Samba mit LDAP. Bin ja gespannt, wenn ich weiter konfiguriere ....

Ich bin ziehmlich sauer auf die SuSE....
