Error while doing key based authentication

We are trying to do a key exchange from Sun solaris server to HP UNIX server. Errro we are getting is as below:-

 
sshd2[6583]: connection from "10.13.240.6"
sshd2[2579]: auths-pam: PAM subprocess returned packet SSH_PAM_OP_ERROR. (err_num: 32, err_msg: General Commercial Security error)
sshd2[2579]: User acremap's local password accepted.
sshd2[2579]: Password authentication for user acremap accepted.
sshd2[2579]: User acremap, coming from 10.13.240.6, authenticated.
sshd2[2940]: PAM transaction resulted in error.
sshd2[2965]: Now running on acremap's privileges.
sshd2[2965]: Received SSH_FXP_INIT
sshd2[2965]: Received SSH_FXP_REALPATH
sshd2[2965]: Resolving path to `.'
sshd2[2579]: Local disconnected: Connection closed.
sshd2[2579]: connection lost: 'Connection closed.'

Can you give OS version of both?
