[OpenAFS] is k5start command not functional at 1.4.12-79 version?

[TIARA System Man]

dear guys,

i was able to use the k5start command at the openafs-1.4.7-68.
somehow, i updated the kernel version from 2.6.18-92.1.6 to
2.6.18-92.1.22 and update the openafs from 1.4.7-68 to 1.4.12-79. i'm
not able to use following command to backup afs into IBM TSM :
***
k5start -l 5d -tUf /opt/tivoli/tsm/client/ba/bin/tsm.keytab -- sh -c
'/opt/tivoli/tsm/client/ba/bin/dsmc incremental'
***

after i use above command, i just get following message.
***
Kerberos initialization for TSM/lupus.tiara.sinica.edu.tw@TIARA.SINICA.EDU.TW
***

and the " sh -c '/opt/tivoli/tsm/client/ba/bin/dsmc incremental' "
part is not executed.

do you have any idea with this? i was use the kstart with 3.13. now, i
updated it to 3.16. however, i still can't not use k5start normally.
i've copied the tsm.keytab file to another afs server which runs
1.4.7-68 with 2.6.18-164.15.1 kernel. that afs sever is able to run
k5start command normally.

sorry to bother you and thank you in advance!!

best, sam
