[cifs-protocol] limits on rDN size in AD ?

[tridge at samba.org]

Hi Hongwei,

We're back to the old question of rDN size limits again!

I just got a DRS replication reply from w2k8-r2 with a CN that has a
length larger than 64. So I suspect that things are a bit more complex
than what we'd discussed before.

The object was:

  CN=89532b80-09fe-445e-afef-965c0d7f7d15\0ADEL:462902b4-1824-4f02-8956-9f934f64fa01,CN=Deleted Objects,CN=Configuration,DC=vsofs8,DC=com

which gives a length of 80.

Are we perhaps supposed to interpret the \0 as a termination character
for the purposes of this length constraint? (note that this is a \
followed by a 0, not a nul byte).

Or perhaps deleted objects are special in their constraints in some
way?

Cheers, Tridge
