Dear All,
After configuring IPMP in 2 fresh Servers (T5520 and T2000) I can't login in any of them using SSH, I can login by serial console then I had to enable Telnet to access.
IPMP works fine.
This is the error in /var/adm/messages:
sshd[1071]: Failed password for lvalle from 172.28.12.95 port 50532 ssh2
The configuration for IPMP I used is:
/etc/hosts:
172.28.11.81 lag-pro-cdrs-01 loghost
172.28.11.82 lag-pro-cdrs-01-e1000g0
172.28.11.83 lag-pro-cdrs-01-e1000g1
/etc/hostname.e1000g0:
lag-pro-cdrs-01-e1000g0 deprecated -failover netmask + broadcast + group ipmp up addif lag-pro-cdrs-01 netmask + broadcast + up
/etc/hostname.e1000g2:
lag-pro-cdrs-01-e1000g2 deprecated -failover netmask + broadcast + group ipmp up
This is the network configuration:
-bash-3.2# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1

I'll appreciate your advice in this regard.

Self solved 
I'm not sure whether was related to the password complexity (/etc/default/passwd), or the fact my user ID was 0 same as root and in /etc/ssh/sshd_config PermitRootLogin was set to "no".
Strange thing login only failed after configuring IPMP.
So you now know where to look if you have this problem I think it was the UID 0 stuff.
