nslcd buffer overflows?

Hi,

Seit ich nslcd installiert hab krieg ich ganz eigenartige Meldungen im
Syslog die mich eher an Buffer overflows erinnern als an normale Logs:

nslcd[3338]: [16ec34] <passwd="pam_unix(sshd:auth"> request denied by
validnames option

nslcd[26547]: [584bcb] <group/member="mark"> no available LDAP server
found, sleeping 1 seconds



Ist das wirklich normal?
Was haben ueberhaupt diese SGML/XML tags in den Logs zu suchen?

Wo siehst da XML?
Sieht so aus als kannst Du Deinen LDAP server nicht erreichen.
