Emmanuel Lecharny commented on DIRSERVER-720:
---------------------------------------------

The dn we receive is really invalid ;
0x64 0x6E 0x3A 0x20 0x75 0x69 0x64 0x3D 0x75 0x73 0x65 0x72 0x2E 0x31 0x2C 0
x64 0x63 0x3D 0x65 0x78 0x61 0x6D 0x70 0x6C 0x65 0x2C 0x64 0x63 0x3D 0x63 0x
6F 0x6D
are the bytes for :
dn: uid=user.1,dc=example,dc=com

And the full received PDU is :

30 25
02 01 02
4A 20
64 6E 3A 20 75 69 64 3D 75 73 65 72 2E 31 2C 64 63 3D 65 78 61 6D 70 6C 65 2
C 64 63 3D 63 6F 6D
(d   n   :         u   i    d    =  u   s   e   r    .    1   ,    d   c    
=   e   x   a   m  p   l   e     ,   d   c   =   c    o   m)
the first chars ( "dn: ") should not be there. Ldapdelete command is bugged,
 I think.
