There's definitely something involved with the size of the request.  For 
example, mixing things up and using:

suaffiliation suprivilegegroup uid

instead of:

suaffiliation suprivilegegroup mail

also freezes.  But with a different read value error:

sasl_read: want=4, got=4
  0000:  00 00 00 52                                        ...R
sasl_read: want=82, got=53
  0000:  05 04 07 ff 00 00 00 1c  00 00 00 00 36 cc 15 1d   ............6...
  0010:  99 41 1e 21 3f dd ac 8d  03 eb 2d 76 b8 5b 08 de   .A.!?.....-v.[..
  0020:  b5 23 41 69 66 9e 62 8f  cf cc 42 35 c7 a7 b2 57   .#Aif.b...B5...W
  0030:  c3 07 7e 59 f3                                     ..~Y.

Where mail is always:
sasl_read: want=82, got=39

Switching out for displayname, we get:
sasl_read: want=82, got=41

Changing to

uid suprivilegegroup displayname

we get:

sasl_read: want=82, got=57


Changing to

uid suprivilegegroup displayname suaffiliation cn

the query works.

There's obviously some flaw in length generation somewhere.
