[Samba] Samba 3.0 AD usage problems

[Catherine Shen]

Dear all,

I downloaded samba3.0-alpha21 and followed each step in "ADS-HOWTO.txt".
But mapping a network directory from a Windows client failed (step 4:
Test your server setup).
(Succeeded in other steps.... Including step 5)
Only local users in the samba server can access the share folder.
(Please refer to the smb.conf listed below...)
And "#kadmin -p administrator" fails with the error message:
"kadmin: Database error! Requeired KADM5 principal missing while
initializing kadm in interface"

My configurations are as followed:

Kernel : Linux 2.4.18
Krb5-devel & krb5-lib & krb5-workstation : 1.2.4-1
Openldap-devel : 2.0.23-4

/usr/local/samba/lib/smb.conf --
	[home]
		comment = root directory
		path = /home
		writeable = yes
		browsable = yes
		guest ok = no
		write list = root,administrator	#administrator is a
Win2K user
		read list =

/etc/krb5.conf --
	[libdefaults]
		default_realm = CATHQ.COM.TW
	[realms]
		CATHQ.COM.TW = {
			kdc = 172.16.21.120
			admin_server = 172.16.21.120 
			kpasswd_server = 172.16.21.120 
			default_domain = cathq.com.tw
			v4_realm = cathq
		}
	[domain_realm]
		cathq.com.tw = CATHQ.COM.TW

/etc/hosts --
	172.16.21.120		catad.cathq.com.tw CATAD.CATHQ.COM.TW

My scripts before starting smbd & nmbd are :
	...
	/usr/kerberos/bin/kinit administrator at CATHQ.COM.TW
	net ads join
	....

Executing "#klist -e" result:
	Ticket cache: FILE:/tmp/krb5cc_0
	Default principal: administrator at CATHQ.COM.TW

	Valid starting     Expires            Service principal
