RHDS - How to decode base-64 encoded values?

Issue

It may happen that a search returns a base-64 encoded value whereas a plain text value is expected.
This typically happens when one adds inadvertently trailing space character(s) to an attribute value.

For instance:

# ldapmodify -D "cn=Directory Manager" -W -x -h <HOST> -p <PORT>
Enter LDAP Password:
dn: uid=user1,ou=People,o=Test
changetype: modify
replace: description
description: My description with trailing spaces       

modifying entry "uid=user1,ou=People,o=Test"

#

# ldapsearch -xLLL -D 'cn=Directory Manager' -W -h <HOST> -p <PORT> -b 'uid=user1,ou=People,o=Test' -sbase 'uid=*' description
Enter LDAP Password:
dn: uid=user1,ou=People,o=Test
