login delay

[Willem Jan Withagen]

Hi,

Running 5.3-Stable from december, this server has a login delay which I 
can not really explain.
Both ssh and ftp react almost direct, only after entering the passwd the 
connections sits idle for > 15 secs.

So something is is taking a while, and since it is both with ssh and 
ftp, I would assume it is the actual passwd verification itself.

Any suggestions as where to look?

Thanx,
