| ## oid2dn returns a string distinguished name (dn) based on the input | |
| ## dotNotation (dot) string value. | |
| ## | |
| ## See Section 3.1.3 of 'draft-coretta-oiddir-radit' for details. | |

| return "" | |
| arcs = dot.split('.') | |
| arcs.reverse() | |
| dn = 'n=' + ',n='.join(arcs) + ',' + RegistrationBase | |
| return dn | |
| ## dn2oid returns a string dotNotation (dot) based on the input distinguished | |
| ## name (dn) string value. | |
| ## See Section 3.1.3 of 'draft-coretta-oiddir-radit' for details. | |
| ## NOTE: case is not significant in the suffix matching process. | |

| return dot | |
| ## RegistrationBase is a global variable that contains a string distinguished name | |
| ## indicative of the location of registration entries within the RA DIT. | |
| ## | |
| ## Tweak as needed. As matching is not case sensitive, feel free to use the | |
| ## proper case-folding scheme desired for your DIT. | |
