To fix the LDAP login failed error when trying to install Groupwise 7 Webaccess or GWIA on SLES Linux:
Go to LDAP Group object for the server (not LDAP server object). On the General tab, uncheck Require TLS for simple binds with Password > OK
Goto LDAP server object for the server, and on the General tab press Refresh NLDAP Server now.
During installation, the WebAccess Installation program requires access to eDirectory by way of LDAP authentication. The LDAP Group object includes an option named Require TLS for Simple Binds with Password, which is enabled by default. With this option enabled, you must provide the LDAP server’s Trusted Root Certificate, which must be exported from the LDAP server, in order for LDAP authentication to take place (typically on port 636) during installation of the WebAccess.
Unless you already have SSL set up, an easier alternative is to disable Require TLS for Simple Binds with Passwords in ConsoleOne, which allows LDAP authentication to take place using clear text (typically on port 389), during installation of WebAccess. After disabling the option, restart eDirectory, install WebAccess, then re-enable Require TLS for Simple Binds with Password and restart eDirectory again.
