samba - May 2009 - Failed search for base: sambaDomainName=MUC, sambaDomainName=MUC, dc=...

Hi,

during debuging with level 10 logfile on my PDC, I saw during the joining 
process off a member server:

[2009/05/29 21:27:20,  5] lib/smbldap.c:smbldap_search_ext(1205)
   smbldap_search_ext: base => 
[sambaDomainName=MUC,sambaDomainName=MUC,dc=mr,dc=lfmg,dc=de], filter => 
[(&(objectClass=sambaTrustedDomainPassword)(sambaDomainName=MUC))], scope
=> [2]
.....
[2009/05/29 21:27:20, 10] lib/smbldap.c:smbldap_search_ext(1269)
   Failed search for base: 
sambaDomainName=MUC,sambaDomainName=MUC,dc=mr,dc=lfmg,dc=de, error: 32 (No 
such object) ()

Why does it tries to search in
"sambaDomainName=MUC,sambaDomainName=MUC,..."?
Anything to worry about or a change to fix?

The full level 10 debug log I put here:
