Technote (troubleshooting)


When the SET LDAPUSER command is used, the connection can fail with:

The user common name (CN) in the SET LDAPUSER command contains a space or the ldapurl option is incorrectly specified.

Resolving the problem

  • In the trace provided, the common name (CN) contains a space.

    (CN=tsm user,OU=TSM,DC=ds,DC=example,DC=com)

    Remove the space in the common name when using the SET LDAPUSER command. For example:

    SET LDAPUSER "CN=tsmuser,OU=TSM,DC=ds,DC=example,DC=com"

  • Use an LDAP connection utility such as ldp.exe to ensure the ldapurl option is correct and the LDAP server is accepting connections

    <ldapurl> port 636, check the box for SSL

    Verify there are no errors in the output
