From http://php.net/session_name :

  The session name [...] should contain only alphanumeric characters. [...]
  The session name can't consist of digits only, at least one letter must be
  present. 

However -- your problem with auth sessions might be fixable by just setting a 
unique $CookiePrefix variable in the field. See for more information:

  http://www.pmwiki.org/wiki/PmWiki/BasicVariables#CookiePrefix

I am actually not certain that PmWiki would work correctly with forced session 
names like yours, but it might.
