Applies to:Sun StorageTek Auto Cartridge Sys Lib SW (ACSLS) - Version 7.1 to 8.2 [Release 7.0 to 8.0]
Information in this document applies to any platform.
Unexpected software limitation reached. Lines in users.ALL.allow file can't be longer than 256 characters.
A customer with multiple ACSLS client servers discovered that there is a limitation of 256 characters per line in the users.ALL.allow file.
In the example below, the client named labore should be able to access volumes owned by owner "csb":
bash-3.00$ cat users.ALL.allow
csb aaaa0 aaaa1 aaaa2 aaaa3 aaaa4 aaaa5 aaaa6 aaaa7 aaaa8 aaaa9 aaa10 aaa11 aaa12 aaa13 aaa14 aaa15 aaa16 aaa17 aaa18 aaa19 aaa20 aaa21 aaa22 aaa23 aaa24 aaa25 aaa26 aaa27 aaa28 aaa29 aaa30 aaa31 aaa32 aaa33 aaa34 aaa35 aaa36 aaa37 aaa38 aaa39 aaa40 labore
bash-3.00$ cat users.ALL.allow |wc -c
acsss_config Option 6 (Rebuild Access Control information) does not flag this as an error and will continue to say that "Access control tables have been rebuilt."
2432 I rebuild_ac_lists.c 1 107
rebuild_ac_lists: Access control tables have been rebuilt.
However, when trying to access volumes owned by "csb", client "labore" will get a "Volume access denied" error:
bash-3.00$ tail -4 $ACS_HOME/acsss_event.log
