openssh-2.5.1p1 problem on redhat 6.2

[John XING]

Hi,

I built rpm from openssh-2.5.1p1 srpm on redhat 6.2,
then installed it. When trying to ssh from other machine,
sshd gives error:

.....
Feb 20 17:54:24 foo PAM_pwdb[925]: (login) session opened for user doe by LOGIN(uid=0)
Feb 20 17:55:15 foo sshd[1342]: Connection closed by 192.168.0.3
Feb 20 17:55:43 foo sshd[1343]: PAM unable to dlopen(/lib/security/pam_stack.so)

Feb 20 17:55:46 foo sshd[1343]: Failed password for doe from 192.168.0.3 port 1121
Feb 20 17:56:01 foo sshd[1343]: Failed password for doe from 192.168.0.3 port 1121

Seems linked to wrong lib? Any suggestions?

Thanks,

John
