Поставь цифру [OU1]
Returns the specified organizational unit component of a hierarchical name; n can be from 1 to 4, as in OU1. In the canonical form of the name, the OU components are not numbered; however, they are counted from right to left so that the first occurrence of the OU label is treated as OU1, the second occurrence is treated as OU2, and so on. Notes/Domino does not accept [OU] as a keyword
