If the user specifies a base DN containing a space, for example, o=U.S. Government,C=US at iPlanet Directory Server configuration time, the resulting DN is truncated to Government,C=US. At configuration time, the DN should be entered as o=U.S.%20Government,C=US.
Workaround: To correct the base DN entry, follow these steps.
Select the top directory entry in the left-hand navigation pane of the Servers and Applications tab on the Console.
Edit the suffix in the User directory subtree field.
Click OK.
