Subject: [PATCH] back-sch-nss: only loop if asked to try again
|
||
|
|
|
||
|
|
slapi-nis uses sss-idmap library to discover user group membership. Its
|
||
|
|
sss_nss_getgrouplist_timeout() function can return timeout errors as
|
||
|
|
well which might cause a busy looping. sss_nss_getgrouplist_timeout()
|
||
|
|
will return ERANGE which is translated by slapi-nis to NSS_STATUS_TRYAGAIN.
|
||
|
|
|
||
|
|
Fixes: rhbz#1967179
