I have setup 389-DS Client which is facing issue to login.
All I did is:
 
1.Run authconfig-tui
Selected LDAP, MD5 Password
next Screen >> [*] TLS
                           ldap://389-supplier.sap.com:636
                           BASE DN: dc=im,dc=sap,dc=com
 
Tried to login but it is not able to see any screen
I tried disabling

#ssl start_tls
And Now it does allow login asking for password.
But When I provide pasword it throws me out of putty.
 
My 389-Supplier is on 636 port and I wonder what could be the issue.
Pls Suggest?
I checked with /var/log/secure:
 
[root@389-ds cacerts]# tail -f /var/log/secure
